Bug#487421: Early boot-time kernel panic with linux-image-2.6.25-2-amd64 (2.6.25-5).
Package: linux-image-2.6.25-2-amd64
Version: 2.6.25-5
Severity: grave
Justification: renders package unusable
Hello all,
I experience early boot-time kernel panic with linux-image-2.6.25-2-amd64 (2.6.25-5)
on my amd64 box.
After having read tons of posts on forums, and particularly:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482773
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=479101
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=479607
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=479607#96
I know that the bug I discovered is closely related to already reported bug #479607
which apparently concerns lilo because:
The bug - kernel panic - happens just before any piece of userspace code being
loaded from initial RAM disk :
=======================================
RAMDISK: Couldn't find valid RAM disk image starting at 0.
List of all partitions :
0100 65536 ram0 (driver?)
..
..
..
010f 65536 ram15 (driver?)
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(22,65)
=======================================
But I have to add food for thought:
Here follow key files on my Debian_amd64 system:

WHERE initrd.img-2.6.25-2-amd64_light is a manually lightened customization of the
original initrd.
Finally, since I only experience trouble - very early kernel panic - with 2.6.25-2-amd64
regardless wether my initrd is heavy or not, how do you explain this strange behavior ?
In hope my report will prove useful.
Sincerely,
Valentin QUEQUET
