Kernel 2.6.36 (sometimes) goes oops on ARCH, Is there a panic log somewhere?

Hello.
I am using arch and recently reinstalled it and the first thing I did (after setting up the modem) was to update everything using pacman -Syu.
This updated to Kernel version 2.6.36-ARCH .

Problem is I some times get a Kernel panic, two actually.
I get a Kernel panic at boot and after a hard reboot I get a second panic also at boot.
It's always like this Panic #1 > reboot > Panic #2 > reboot > works fine.

I searched /var/log/ for anything about it but found nothing, probably because it happens before the file system is mounted, so I have pictures instead (sorry I'm a horrible photographer).

Panic #1

Panic #2

I should also note that I am somewhat of a newbie and have no idea what they mean.

From /boot/grub/menu.lst

Code:

# (0) Arch Linux

title  Arch Linux

root  (hd0,0)

kernel /vmlinuz26 root=/dev/disk/by-uuid/42f77199-728b-454b-a6d7-96d542f729d8 ro vga=773

initrd /kernel26.img

root used to be root=/dev/sda2 but I changed it cause I thought the nodes might change but I still get the same panics.

Where do I go from here ?

I would first make sure that your /etc/fstab refers to the uuid

Code:

UUID=42f77199-728b-454b-a6d7-96d542f729d8 / ext4 defaults,noatime 1 1

then, I would regenerate the initramfs

Code:

# mkinitcpio -k 2.6.36-ARCH -c /etc/mkinitcpio.conf -g /boot/kernel26.img

Thank you.

I changed fstab to be :

Quote:

# /boot
UUID=a0b3faee-75ac-4180-a9c0-dfa82ebe70bc /boot ext3 defaults 0 1
# /
UUID=42f77199-728b-454b-a6d7-96d542f729d8 / ext3 defaults 0 1
# /home
UUID=36f6a699-4e7d-4805-91d7-e77d1798c531 /home ext3 defaults 0 1

and ran " pacman -S kernel26 " again and it regenerated initramfs.
As the panics happen randomly at boot I can't know if it will work until I reboot several times.

Edit:
That didn't work..
But I then did " pacman -S grub udev " to reinstall both and so far after 5 reboots I got no panics.

Edit 2:
I take that back.
It's panicking again at random.

Use memtest just in case.

Ran memtest, found no errors, neither has fsck.

This is also happening to Slackware users who upgrade to the 32 bit current version.

After trying out multiple new kernels with no effect I now think that the problem relates to udev-165.

When I downgraded udev to udev-164 then the kernel panics stopped.
