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.
