Hi there.

I got an interesting kernel panic, while trying to mount a
Solaris-mistreated partition (a partition where I _tried_ to install
solaris x86, but never went through..).

Mar 21 22:35:55 sicel-home-1-4 kernel: EXT2-fs warning: mounting unchecked fs, running e2fsck is recommendedMar 21 22:35:55 sicel-home-1-4 kernel: attempt to access beyond end of device
Mar 21 22:35:55 sicel-home-1-4 kernel: 08:11: rw=0, want=516102, limit=515297
Mar 21 22:35:55 sicel-home-1-4 kernel: Kernel panic: EXT2-fs panic (device 08:11): read_block_bitmap: Cannot read block bitmap - block_group = 63, block_bitmap = 516101
Mar 21 22:35:55 sicel-home-1-4 kernel:

This lock the kernel, and its 100% reproducible.
Sure, they are some weird bit sequence on this partition, since the
installation of solaris seem to have touched it, but this does not
explain a kernel panic. I use mount 2.6d-1 (that come with one of the
latest debian "unstable" snapshot), was root when doing that, have
kernel pre-2.0.30 with msr patch, libc-5.4.23-2, kernel compiled with, p5-166, 32MB ram blah blah blah.. Last time that I ran memtest,
it was fine, so don't come to me saying "He, this must be a bad simm's" :)
CPU fan is running at full speed :)

The disk where lye this faulty partition works pretty well, I will keep it
this way for further investigation. Someone with a good knowledge of EXT-2
could be helpful..

Regards, Philippe.
