[Bug 42909] Re: kernel panic at boot

[Roshan Shariff]

I also have a Toshiba Satellite M20 with the same problem. The Live CD
works fine, but an installed system panics while "Mounting Root
Filesystem" with IIRC the same error as Carmelo reports. Rarely, it
doesn't panic at that step, but invariably panics while logging in. If I
manage to get to recovery mode, it usually panics in short order. This
behavior seems like Bug #45636.

This laptop has a SATA hard drive, which is probably the source of
errors, since the live CD works fine. Strangely enough, mounting
filesystems on the hard drive from the Live CD works, though I have not
thoroughly tested this. This problem seems to manifest itself only when
the root partition is being mounted from initramfs.

The problem went away when I installed the 2.6.15-20 i386 kernel from
the Dapper Beta CD. The problem is present in the final Dapper -23
kernel and the updated -25 kernel. However, the laptop sleep mode
doesn't work in the older kernel, while it does work on the newer
kernels (tested from the Live CD).
