Hi... I saw your post in the lkml archives (I'm not subscribed either). I think I'm having either a very similar problem, or the same problem that you are.

Similarities:
Can't mount root, kernel panic
Only happening in 2.5.62-ac1 (I haven't tried any other 2.5.6x kernels)

Differences:
        Using IDE root disc
        Using devfs
        root, which contains /boot, is ext3

I think something about device handling may have changed which is causing this problem. (for me, devfs started needing a root= option since about 2.5.50). Additionally, when the kernel panics, does it specify the correct major/minor device number? Mine uses the wrong one unless I use rdev, and then panics with the correct one (/dev/hda2, 0x0302)

These are the relevant entries in grub's menu.lst:

timeout 5
default 0

title 2.5.62 ac1
root (hd0,1)
kernel /boot/kernel/62.5.2k-ac1 root=/dev/ide/host0/bus0/target0/lun0/part2

title 2.5.51
root (hd0,1)
kernel /boot/kernel/51.5.2k-br root=/dev/ide/host0/bus0/target0/lun0/part2

the second entry works fine, but the first entry panics and gives me the same message you described.
