Kernel panic on upgrade from 2.4.18 to 2.6.17-2
Hi list,
After an apt-get install linux-image 2.6.17-2 I get the following:
"VFS Cannot open root device "hda2" or unknown-block (0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing VFS Unable to mount root fs on unknown-block (0,0)
<0> Press Stop-A (L1-A) to return to boot prom."
The silo.conf is:
partition=1
root=/dev/hda2
timeout=100
image=1/vmlinuz
label=linux
read-only
As the partitioning hasn't changed I'm at a loss to understand why this error is occurring especially as when I change the vmlinuz link back to the old kernel everything 'just works'.
Boot prom acknowledges the kernel as 2.6.17-2 on the way through.
I've copied the /, /boot, df and fstab output below in case its relevant.
TIA
John
