[linux-lvm] RE:Unable to mount root fs after kernel upgrade



Fred,

Here some info after I changed the kernel image with rdev.

I tryed to boot the system after I changed the root using rdev
but this didn't change the behavior.
I also tryed at the boot prompt <image> root=/dev/vg00/root

But I found an other error in de console log when trying to boot the
new kernel :

Here it is:
cramfs: wrong magic
Kernel panic: VFS: Unable to mount root fs on 3a:00


Maybe the error message about cramfs can give me some information to solve
the problem.
