Good luck with the 3.2_rcN series! especially with more than 130k+[addition]/90k-[deletion] or so of diffstat. I made a little effort to follow a little that long awaited 3.1 kernel series with its 10 rc releases, well, too tired to follow a weekly update. Actually I put an [git based] ebuild on my shared overlay with a few goodies, that's the tiresome part. I'll quietly follow the stable tree for now. As the 3.1.1 and 3.0.9 were released Friday with DRM/radeon/i915 fixes, I'll try to update two ebuilds with bfs-414 fixes this weekend if I can. That's all. I would do the update in case I ran into trouble [BSOD(tm), black screen of death with drm-ed drivers] with kernel 3.0.8 or 3.1.0 which happened with previous kernel versions.

I'm using a few bits and pieces of 3.2 in my 3.0.9 kernel (drm, dvb, the new Marvell UMI driver). No issues on that front so far :)

I'm ussing it in a new machine at work. The only problem so far have been the consolefb using kms and uefi (I have tryed ussing efifb and force the kernel to use it without luck). I can't see anything from console!!!

@tclover:

thanks !

the 3.1 series was working quite nicely for me, but the changes (especially for btrfs, etc.) are quite attractive - so I'd like to try them out from time to time [currently still some issues - changed a eSATA-cable some days ago so will try it again in a few days/weeks - hopefully it works then ^^]

yeah, drm was another reason I updated - bfs currently doesn't "cut it" for me [haven't tested for some tie] - so I'm trying mainline some more


@genstorm:

good to know - thanks !

in case 3.2 proves to cause trouble I'll revert to 3.1 + patches from 3.2 ;)


@cruzki123:

O.o

did this get resolved meanwhile ?





ok, got another BUG message - seems there's some issue [real BUG] with reiserfs + genkernel copy operation to /boot (reiserfs) on 3.2 kernel

so I formatted it with ext3 for now (due to lack of troubleshooting) and it worked ...

No, I didn't. I suspect that is related to the screen resolution that is getting the fb from the monitor. I suppose I have to force it but i don't remember how to do this. Moreover, is a "pseudo-production" system and I can't work on it freely. When I have time I will do another try.

After the last i915-drm commit, the following happens seconds after logging into kde(-4.8_beta2):

Code:
[   57.640146] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[   57.640156] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[   57.647377] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 4730 at 4711, next 4737)
[   58.149081] [drm:i915_reset] *ERROR* Failed to reset chip.


(GPU hung, kwin crash)

Reason: xf86-video-intel(-9999) built without USE="sna"

I switched on the sna flag and so far it works fine (I suspect the huge input latency currently is related to the last bits of libreoffice-3.5.9999 being finished) - previously, sna was a royal pita.

EDIT: I stand corrected! Somehow, firefox-8.0 (no change there - I'm puzzled) is responsible for the crash. I've changed back and forth xorg-server-1.11.2/3 as well as 3.2-drm-snapshot-12-17/12-09, xf86-video-intel-9999/2.17/sna/-sna, updated util-macros and mesa-9999 to without success.

EDIT2: Completely different error - it's a cairo breakage caused by qt-4.8....

ok, seems I was able to trace back that issue:

it's cleancache & friends (zcache, etc.) being compiled into the kernel - this leads to instabilities & issues with btrfs,

when compiling the kernel without it - it's fine & btrfs is usable

unfortunate due to less performance but since I currently need btrfs (smaller disk w. growing amount of data) - there's no other way [at least for me, testing & troubleshooting not possible right now]

seems like latest upstream-changes (starting with 2.6.39 ???) broke it




a known issue with was supposed to be fixed in virtualbox 2.1.4 seems to be still there with kernel 3.2-rc6 (not directly caused by the kernel but related to the 3.2 kernel version):

I just manually compiled 3.2.0-rc7, and on first boot had the same thing happen. Compile went normally. (3.1.6 works great). Using my lean config file, which has always worked for all earlier kernel versions

I got into kde-4.7.4 normally, and for some reason I had to put in my wpa passphrase into wicd, and while doing that suddenly everything crashed to a black screen with similar text as kernelOfTruth's last post above.

Couldn't do anything as all was locked up, with keyboard lights flashing. I did notice the

lines were similar (but not Packard Bell stuff).

This is on my main box- amd 1090t x6, asrock 880, 8gb ram, etc. Using ext3 for FS. I looked in all the logs, but didn't see where it crashed (no section that was like what I saw on the black crash screen. :(

I'm quite sure this is an upstream issue - I'll have to check the openafs lists. In the meantime I thought I'd add it here, for informational purposes.

Just did a vanilla 3.2.0, and a gentoo-sources 3.2.0, and both have problems with stopping kdm/xdm, wicd, and a few others.

Can't get wicd wireless to work- wicd is completely greyed out. This system functions perfectly (including wicd wireless) with any other kernel for years, including 3.1.- through 3.1.7. All required modules are loaded with 3.2.0, but wicd still doesn't work. Just to be sure, I ran python-updater (again). Revdep-rebuild reports all consistent, and all config files are correct. Only thing I can figure is that something changed in 3.2.0- either still a 3.2.0 bug, or I'm missing some needed kernel config change. Haven't had any usable 3.2 version yet in Gentoo on any system. :( When I boot back to any 3.1.x version, all is perfect.

Can anyone confirm a working 3.2.0 (or rc) yet, so I know it's only on my system and I need to re-assess my kernel config and my system configs? I'm not a newbie on this kernel stuff- done many hundreds for years. Can't understand why I've having such a problem with 3.2.x's.

Based on a suggestion from on the openafs-info list, I made a local ebuild for openafs-1.6.1_pre1, along with its kernel module. That builds clean on x86_64, and I'm building it on x86 now.

Got the same trouble when patching drivers/net/wireless/iwlwifi from 3.1 to 3.2 - there is a change in iwlagn raised by make oldconfig, so I configure it just the same as 3.1 - nil success.

Is this wireless problem specific to wicd? Can these devices be run by the Gentoo initscript system and wpa_supplicant?

I'm seeing the same wicd wireless problems (with my usb wireless adapter) on both Mageia Cauldron (Mandriva fork), and Arch Linux testing, on all 3.2-rc's and 3.2.0 final, while all the 3.1.x's work perfectly with my current config settings on all distros.

I'm thinking in my case it might be related to the r8712u staging driver I'm forced to use for my Rosewill RNX-N180UBE Wireless Adapter , as there appears to be some "update" activity there (3.1 and 3.2 versions are different sizes). IIRC, a few weeks ago I think I noticed somewhere in a 3.2 kernel changelog a new patch for that driver, but didn't think much about it at the time.

Maybe the /lib/firmware packages I currently have (RTL8712U and rtlwifi) that so far have worked with all 2.6.xx and 3.x.x kernels are NOT compatible with any of the kernel 3.2.xx's?


UPDATE: FWIW, I just compiled a 3.2.0-gentoo-r1 on my WIRED box without wicd/wireless (just using a default eth0 cable connection), and it works fine. So, I guess that confirms the 3.2.0 kernel networking stuff is functional, and my problem is wicd version with kernel 3.2.x, and/or a buggy r8712u kernel wireless driver/firmware. At least that's my current theory. :roll:

UPDATE 2: Installed/configured wicd on my wired only box instead of NetworkManager, and that works normally with 3.1.x AND 3.2.0-gentoo-r1 kernels. :D

My conclusion is that my problem with the wireless wicd might not be wicd itself with the 3.2.0 kernel, but that the newer 3.2.0 r8712u staging driver my usb wireless adapter uses is the problem, even though it and usb-core loads normally. When trying to connect with wireless systems, the wicd gui interface won't fully open (greyed out, and totally empty, as if it's hanging up).

Guess I need to try some other usb devices to rule out other more serious usb 3.2.0 problems. However, I'd assume they wouldn't release a 3.2.0 that still had major usb bugs.

FWIW, I have a work-around for my wicd and wireless connection failures with all 3.2-rc's and 3.2.x's.

I simply copied over the entire linux-3.1.9/drivers/staging/rtl8712/ folder to the 3.2.0 kernel source (replacing the newly patched 3.2.0 version with the 3.1.9 version), and recompiled 3.2.0 using my current config file, and wicd and wireless now work normally.

So, apparently in my case the problem seems to be the newly patched 3.2.0/drivers/staging/rtl8712 driver.

Not sure if this is a general regression or one just specific to my system, as the r8712u driver is required for what seems to be a rather obscure (but great!) Rosewill RNX-N180UBE b/g/n 300Mbps usb wireless adapter. Probably not too many people use this particular adapter, but the latest 3.2.x r8712u versions are currently not working. Guess the other T-link wireless adapter using the ath9k driver I just ordered won't be necessary after all, as long as I use the 3.1.9 rtl8712 version with all 3.2.x kernels. :roll:
Hope the kernel guys fix this up soon.

Has this information somehow been fed back upstream? Looks like the right names are in "/usr/src/linux/drivers/staging/rtl8712/TODO":

Code:
Please send any patches to Greg Kroah-Hartman <greg@kroah.com>,
Larry Finger <Larry.Finger@lwfinger.net> and
Florian Schilhabel <florian.c.schilhabel@googlemail.com>.

No wifi trouble anymore here with 3.2.1 :)

Kernel 3.2 presented a few problems...

I come back to Kernel 3.1.6, which works nice.
I had a problem in my iwlagn driver in wpa_supplicant as previously related, but it was fixed with this patch and now wpa works perfectly: https://bugs.gentoo.org/attachment.cgi?id=297759&action=diff

What problems? I seem to be running 3.2.1-r2 on one system happily. I was thinking of moving another to it. Neither is a laptop, both are wired, if that matters.

On all 3.2.x and even 3.3.0-rc1, I'm still having the same wicd and staging/r8712u usb wireless adapter driver problems mentioned a few posts above.

I contacted Larry Finger (a kernel dev wireless stuff expert) and he is working on this. He even got the same Rosewill usb adapter I'm having trouble with, and installed Gentoo in a VM, plus emailed me a firmware package he thought might help. Unfortunately, I had already tried the firmware, so no luck there. :?

On 3.2 I have gotten some 3.2.1 and 3.2.2 kernels to boot normally with the r8712u driver and wicd somewhat working (at a so far unacceptable link and signal quality level).
Never gets better than 40% (usually much less, and random drop-outs), whereas if I replace the 3.2.x source staging/rtl8712/ directory with ANY version from a 3.1 kernel, and recompile, on reboot to 3.2.x wicd and r8712u wireless work normally at a 98% rock solid connection.

However, on my systems this is the only complaint so far on 3.2.1 and 3.2.2, but probably there are a few more random driver problems out there to be discovered. 3.2.2 does seem a little sluggish at times.

Same problem with 3.2.x kernels on all distros I have tried.

There are also ongoing sound problems in >=linux-3.2 including the latest 3.3 git. I didn't catch that at first, because I don't use my internal mono speaker too often - that one is broken - while the headphones output on notebook and docking station work fine.

Both 3.2 and 3.1 are unstable on my AMD Opteron. The video always seems to crash within a day. This is using an AMD HD 4870 and the ati-drivers.

When it crashes, one CPU core goes to 100% and whatever process the video card was using refuses to die even with 'kill -kill' by root. Even a reboot fails. I have to physically shut it off and then I have hard drive corruption that needs to be fixed. No problems with 3.0 on the AMD.

No apparent problems with 3.2 on an E7600 or 3.1 on an E2160, both using the nvidia-drivers for the video cards.
