I updated the linux sources (debian package) from 2.6.18 to 2.6.20.

However, the new kernel does not boot: it freezes with a kernel panic
when trying to mount the root partition...

On other computers (desktops) this kernel update succeeded without any
problem...

Someone please tell me if I'm wrong, but I think recently someone here
said that 2.6.20 has dropped the names for hd* and all drives are now
sd*.   Could that be your issue?  What are you telling the kernel to use
as a root fs?

Perhaps the other computers didn't have any IDE (/dev/hd*) drives.

I am currently on 2.6.20 and still have /dev/hd* devices. But then
again... I am me.

well, actually, on the desktops where this kernel works I have only /dev/hd*, while on the laptop where it does not work I have /dev/sda as the main hard disk (where the root is).
