Both boot up quite fine and the USB devices are now available, so thank you very much.

Here's my output:

You're most welcome, and it looks like things are running quite nicely according to the dmesg's you sent.

Cheers,
Pappy

dufeu,

Just checking to see if you have kernel issues, or if you're sharing.

Cheers,
Pappy

Sharing. :D

I've found your commentary on kernel settings a very helpful addition to stuff I already knew. So the posted kernel configurations represent my best efforts to date.

I'm still researching this, but it looks like for x86 kernels, the 2.6.33 kernel no longer includes setting CONFIG_WIRELESS_EXT. That seems to be replaced by CONFIG_WIRELESS_EXT_SYSFS or perhaps CONFIG_WIRELESS_EXTENSION. Since I don't program this isn't clear to me. The bottom line is that ndiswrapper will no longer emerge on my laptop. This isn't a problem for me as I no longer need ndiswrapper, but it's something for someone to look at. It's very strange since grepping for CONFIG_WIRELESS_EXT shows it in a lot of places in kernel source. It did occur to me that it's appearance might be conditional, but darned if I can find where to enable said appearance!

Regarding XQYZ' issue with USB. I can see he's quite happy with the correct answer! I have two observations to add to this.

1) My experience with some nVidia chipsets on some motherboards is that you cannot have UHCI in the kernel. For such chipset/motherboards, the 1.X USB ports won't work if both UHCI and OHCI are present. USB 2.0 ports require EHCI in all cases. Therefore, with nVidia based motherboards, my default is to turn on OHCI and EHCI and explicitly leave UHCI off.

2) Also from personal observation. In theory, since Intel based chipsets use UHCI for USB 1.X, then leaving UHCI on and leaving OHCI off should work fine. And in fact, it does work fine. However, I encountered something interesting with laptops which still use PC Cards. It turns out that PC Card based cellular network devices work by using their own built in USB servers. i.e. the driving cellular hardware is the same cellular hardware as used in a cell phone network USB device. This makes the manufacturer's life much easier of course. But the USB device built into all the cards I've had access to require the OHCI driver!

The bottom line is that I leave EHCI, OHCI and UHCI on by default unless there is an nVidia chipset involve in which case I leave UHCI off.

Wouldn't I love to get a hold of something like that and see if I can make it scream!? Woohoo! Six cores, 3.33GHz, and hyperthreading. That would make one hell of a web server!

Toy value...oh yeah! That would make for one damned serious Tinker Toy.

I'd do whole world compilations in an hour or so. That would be so cool. I'd have to train my eyes to move even faster than they already do. I can almost feel the headache now. Ah, it is a sweet pain indeed.

I wonder if I plug Intel on the site if they'll give me one. I'm not Stephen Colbert, but then again, I do have my fans. hehhehehe.

Ok, now back to the real world.

Cheers,
Pappy

Did you all look at the power dissapation on that weenie roaster? 130 watts!!! :o

How hot does a 100 watt light bulb get? You better have some serious cooling setup for that thing! 8O

That is only under load. Anandtech did some power measurements on it that showed that it only consumed 6.3 DC Watts at idle and slightly exceeded its TDP under load:

It can't run any hotter than the P-IV file server. That thing is almost like a space heater on those chilly Texas "winters".

Well, if you're not using its power, then it won't get so hot, but then why did you spend over a grand for it if you're not using it? 8O

I did work on a project last year where it would have been nice to have a 16 socket server board populated with those chips though... :)
It was sort of a rainbow tables reverse crypto thing where we had to try a known set of keys to decrypt a message, and we also needed to get some good thruput out of it. Having 192 threads working in parallel would have helped a lot. Its amazing that a lot of speed problems are best solved by just waiting for the next round of hardware... :wink:

I still say the sheer toy factor is most important.

... and the ability to fry (small) eggs of course.

Hmmm ... isn't there a kernel setting for that? Pappy?

You forgot "incinerate". That's the setting that allows the magick smoke to release, thereby ending the life of the device. I've seen that one, too. K6 chips melted into their sockets...what a sight!

hehehe

Pappy

Indeed, when AMD release their first CPU back when Intel was producing the P3 450 Mhz, I saw a couple of Athlon burning when I was a student in a computer shop.

AMD CPU were the best toaster that I ever seen.

I'm amazed the Athlon in the web server doesn't run hot. But it doesn't. I'm hoping a once a month cleanout of the PS and other fans will keep that from happening. It's worked on all my Intel machines.

Cheers,
Pappy

If I recall correctly, the original Athlon didn't have an internal temperature sensor. It was the next stepping which finally included a built in sensor.

I remember clearly my initial surprise the very first time I had an Athlon based PC shut itself down for overheating. It was a system I built for my mother. Since she smoked at the time and the system was on the floor ... Talk about disgusting!!

Once I saw the inside of it, it was a wonder to me that it ran as long as it did before turning itself off to protect itself! I still have some working Athlon 2500 and 3100 based systems in FL. With 1 gig RAM even ...

Then again, I still have an original Pentium 133 configured with several ISA based NICs setup as a firewall. 64 megs RAM ... Yes. It still boots a Gentoo based CLI only setup with a 2.4.X kernel.

Pappy? Do you have any 2.4 kernel seeds? I'm thinking of upgrading my old firewall and putting it back into service.

No, I don't.

While I suppose I could set some up, as far as I'm concerned, the 2.4 kernels are fairly antiquated. They may be backporting certain symbols and so on, but with today's current crop of high-powered systems, the 2.4 kernel is really unneeded. When you couple this with the fact that certain things, such as glibc require 2.6.27 or greater kernels, that makes the argument for setting 2.4 kernels up rather moot.

Cheers,
Pappy

Talk about old geezer machines... a couple of years ago I finally retired a Packard-Bell P-75 that had been performing originally asa firewall, and then as a secondary DNS. I remember when I got my first P-133. It was to replace a fried p-120 that only lasted less than a year. The P-120 was a replacement for a 386-20, which was my first Unix machine in 1989. It ran 386/ix from ISC at first. It was upgraded to slackware in 1993. It was replaced by the P-120 in 1995. It had 16 MB of ram and a 100 MB SCSI disk. It also had a 1600x1200 display, but only black and white. Seventy some odd floppy images to download using uucp between midnite and 6 AM for a week at 2400 BAUD, then feed them all back in to get the basic system running.

Those were the days. :roll:

These days are better. :)

I spent an annoying 24 hours (counting sleep) getting gentoo-sources 2.6.31-r6 to boot on my backup server. It runs lvm on the root filesystem, so it needs and initramfs/initrd to boot. It had been running genkernel-x86_64-2.6.29-gentoo-r5 with a manual config and letting genkernel set up the initramfs, but with recent breakage in genkernel's ability to do that, I wanted to free myself from genkernel bondage. I built the 2.6.31-r6 kernel manually, along with a manually built initramfs. Seems no matter what I tried, it wouldn't get thru the initramfs, but paniced every time. :evil:

Since the screen only has 24 or 25 lines during this phase, and it never got past the pivot root, I had very little to go on except try this, thry that, throw the whole thing out the window and sit down and cry. Boy, was I frustrated! :cry:

Then I noticed a little hint of the real underlying problem. I was seeing echo messages I had placed in an earlier build, but they should not have been in the current build.

Turns out problem one was I was booting off /dev/sda, but seeing the root filesystem on dev/sdb. This can easily happen with udev and hot swappable sata drives. :?

MORAL: With udev you need to make sure your devices are where you think they are! :oops:

So I pulled the /dev/sdb drive out of the sata backplane and tried again. Not even close. Seems I had bolluxed up the config and the init so badly the best thing to do was just start over. So I fetched Pappy's seed for this kernel. The box has an Intel core2/quad with 8 gb ram, 5 1.5 tb drives, and a blu-ray burner. I did the lspci -n and pasted it into the Debian device analyzer page. Then I configured the kernel.

When I built the kernel, I got a weird warning about clock skew, so I stopped it, checked the time, and it was goofy. Seems the hardware clock on the motherboard was several hours slow. So I set the time in the system (not the motherboard hardware clock), and re-ran the kernel build. Everything went OK, so I copied the kernel to /boot and gave it a whirl. Still no joy. :evil:

This went on for hours, with me trying everything I could think of twiddling with the config and the initramfs. Still no bootem. :evil: :evil: :evil:

Finally :idea: I thought, "Maybe that clock skew thing irreparably goofed up the timestamps of some of the kernel files, and its not building what I think it is." So I made sure I had a copy of the current config, then I did a make mrproper. Next I copied the saved config back and rebuilt the kernel. At this time, my wife called, and I had to leave the machin building while we went to play with our great nephew, age 3.

A couple of hours later, when I got back, the kernel was obviously finished building, so I copied it to /boot and rebooted.

The thing came right up !!! :D :D :D

MORAL: If you see a clock skew warining, do a make mrproper before you pull your hair out. :wink:

Trying to use your config for zen kernel and when I do I can't find any drivers for the RTL-8139/8139C/8139C+ (8139cp,8139too)?
