Latest working kernel version: 188.8.131.52-50.fc8
Earliest failing kernel version: > 184.108.40.206-50.fc8
Hardware Environment: x86_64 two xeon 3.0 GHz CPU/ ASUS ncch-dl MB
Software Environment: Fedora 8
Problem Description: During boot the keyboard becomes unresponsive/dead. The keyboard stops working after a finite period of time and can be monitored by pressing the caps lock on and off until the light no longer responds.
Steps to reproduce:
Install kernel > 220.127.116.11-50.fc8 using YUM boot to that kernel keybaord stops working, get second PC ssh into first pc shutdown first pc.
I've also posted this to Fedora bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=446763
I'm currently going back to a pure kernel.org kernel 18.104.22.168 installing and then will try patching until it becomes faulty (if it becomes faulty). I've tried booting into kernel 2.6.25 and that works fine.
Building kernel 22.214.171.124 directly from the .kernel.org website using the make instructions from the readme and the config info inherited from 126.96.36.199.3-50 - not altering anything in the menuconfig stage, gave me a kernel which I could boot with no keyboard issues and make nvidia drivers for - a usable kernel.
I will try kernel 188.8.131.52.7 from the website and if that works it must be down to a fedora related patch/mod.
I have now built the 184.108.40.206 kernel and booted successfully. This would therefore point the problem at one of the fedora patches added to the 220.127.116.11 kernel. I'll now go through their patches and remove them from the rpm src until I can find the one at fault.
nice find ;)
if this turns out to be a fedora issue - can't this be closed then ?
I would suspect the answer is yes. Although I've found that you can't do make binrpm-pkg using the O option to specify an alternate path. If you do it fails to find the .config file. Instead you need to do make then make binrpm-pkg in the same src directory. It is also annoying that make install and make install_modules will create the *img file but the rpm doesn't.
I don't suppose any of these comments really need to be in this bug?
Before closing the bug would it be ok if I try and post the patch which is causing the fedora issue? There are 160 patches it may take me a while. Plus following the changelog comments makes it no easier a task.
Before starting out on the patches I thought it would be worth comparing the 18.104.22.168 and 22.214.171.124-92 config files. (attached).
Comparing this with the changelogs could activating I2C_PIIX4 be the culprit?
# CONFIG_I2C_PIIX4 is not set | CONFIG_I2C_PIIX4=m
I'll try the stock kernel with this turned on to see.

Diff -y on config-126.96.36.199 and config-188.8.131.52-92.fc8
Diff command run on the two config files used to make the kernel. The non-fedora one works while the fedora one kills the keyboard at boot.
I am having a similar issue, however I cannot even Ctrl-Alt-Del as the PS/2
keyboard is completely unresponsive after "Enabling /etc/fstab swaps: OK" and
can only hard reset the box. See https://bugzilla.redhat.com/show_bug.cgi?id=444694
This may have been resolved.
A patch has been put forward by the redhat/fedora guys it is suspected that the git firewire modules are to blame when coupled to a ALi firewire/usb combi card.
allows the stock fedora kernel to boot. Likewise compiling the stock fedora kernel without the git firewire patches allows for a stable kernel.
I think you can now close this.
It is a regression in mainline too, post 2.6.25.
Fix posted and verified with a newly acquired ALi based card: http://marc.info/?l=linux1394-devel&m=121380606431945
I will try to get it into mainline by the end of this week.

Fix merged into upstream 2.6.26-rc7.
J and Naveed, thanks for locating the source of the bug. Fixing it was easy after you did all the debugging work.
