Just curious, anyone knows anything about a gentoo-kernel patched to be compiled with ICC instead of GCC?
I heard that some time ago intel supported these kind of stuffs, and that the speed up was significant...

i have tried every patch online but it just doesn't work. there is a linux-2.6.22 kernel
floating around online which should work but that doesn't work for me either.
am using icc latest version. we have to wait until some pc guru comes around with something.

Is there a 2.6.28-zen9 planned? I'm one of the unlucky ones hit by the MCP55 bug supposedly fixed in patch 4.

Also what would happen if I did a "patch -R < patch3 ; patch < patch4" to zen8? :wink:

2.6.29-rc2-zen1 has a bug when setting max cpu count. Seems that logic is inverted (when unselected, one can set max cpu count).

You could always use master-2.6.28, updates from linus are usually in there same day as they are out and it's stable to be using that.

But for the record, zen9 is out now, as is rc4-zen1 ;), then master-2.6.28 and master would read zen10 and zen2 respectively :P

Earlier versions of zen were unstable for me, usually within 12-24 hours the entire drive would lockup and turn read only. Quite an annoying bug! Anyway zen9 finally fixed it.

Just want to throw my observation out there. I have had similar issues as you
guys and the problem turned out to be the nvidia driver. I get this problem
randomly with any driver in the 180.xx series all the way up to 180.27. I can
easily change to the 177.80 or 180.29 driver and problem is gone. So if using
nvidia i would recommend testing with diff drivers.

I don't know if the probability is higher that you read it in the zen-sources.org forum or here BUT:

please include: http://git.eu.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ab4c1424882be9cd70b89abf2b484add355712fa

in the next 2.6.28 kernel-release

dm: support barriers on simple devices

Implement barrier support for single device DM devices

This patch implements barrier support in DM for the common case of dm linear
just remapping a single underlying device. In this case we can safely
pass the barrier through because there can be no reordering between
devices.


many thanks in advance

ok, I don't know if I need the other patches from 2.6.29-rc* but it STILL doesn't seem to work for me:

patch #4 for one - http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.28.4

and what fixed my issue was this

Code:
sata_nv: fix MCP5x reset
   
    commit 2d775708bc6613f1be47f1e720781343341ecc94 upstream.
   
    MCP5x family of controllers seem to share much more with nf2's as far
    as reset protocol is concerned.  It requires heardreset to get the PHY
    going and classfication code report after hardreset is unreliable.
    Create a new board type MCP5x and use noclassify hardreset.  SWNCQ is
    modified to inherit from this new type.
   
    This fixes hotplug regression reported in kernel bz#12351.


still stable, not one hd-related crash since (no crashes yet actually lol).

ok, screw that patch

I can't open my LUKS partitions anymore with that patch applied,

please DO NOT add it to zen-sources

thanks

Okay. Since these are in the Zen sources, I'll ask here. You can move this to the Reiser4 Tuning thread if it more appropriate there.

Reiser4+cryptcompress question. How does performance differ with the BFQ and the V(R) I/O schedulers compared to CFQ?

since I'm suffering from the ncq / seagate firmware BUG the performance is abysmal compared to cfq :wink:

under normal circumstances BFQ should be much more responsive under heavy load,

V(R) I/O should be comparable to deadline but better

I added a kernel config archive/db feature to our website so that you can upload working configs for a particular computer manufacturer/model. Feel free to upload non zen configs as well. vanilla, mm, etc. are all welcome

no prob at all :)

edit (a little debugging): look like i create a new kernel version in the first steps.
when i select this version before submitting I have it correctly displayed in the list one time, after submitting a new version entry with the same name is created and you have two versions with the same name in config lists. ;)
