Package: linux-image-2.6.26-1-486
Version: 2.6.26-5
Severity: normal

I just upgraded my ThinkPad 760 ED from Etch to Lenny. Everything in
the userland works fine under the Etch kernel, but the Lenny kernel
can't find it's root filesystem. It says something like "Waiting for
root file system" and then falls into an initramfs shell after a
minute or two.

Etch's 2.6.18 kernel boots fine. It also immediately finds and mounts
the root fs.

Since I could neither find any /dev/hd* nor any /dev/sd* using the
initramfs shell of the 2.6.26 kernel, I suspect the kernel messages
marked with a "<--" below to be the cause for not finding the root fs:

done.
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/hda3 does not exist. Dropping to a shell!

(All text above transscribed from the screen manually, so there may be
typos in. :-)

/proc/cmdline contains: root=/dev/hda3 ro pci=biosirq

(pci=biosirq was a try to get around the issue, also happens without,
see below.)

/proc/modules contains:

piix 6532 0 [permanent], Live 0xc380a000
ide_core 91444 1 piix, Live 0xc3844000
floppy 47620 0 - Live 0xc381c0000
thermal_sys 10784 0 - Live 0xc380600

/dev/ does not contain any hd* or sd* devices.

Google found the line "PIIXa: bad irq (0): will probe later" only
twice, and one of these cases was a ThinkPad 760 ED, too:

http://lists.infradead.org/pipermail...ly/000150.html
http://geoffair.net/fg/txt/DMESG-04.TXT

Adding pci=biosirq as suggested in the first link didn't change
anything.

"PIIXa: IDE port disabled" isn't found at all by Google.
