I ran apt-get update and apt-get upgrade this morning on an old server (Debian Squeeze) and the system won't boot now. I get the error
kernel panic not syncing: VFS: unable to mount root fs on unknown -block(0,0)
One of the updates was to kernel 2.6.32-5-686. I can boot in to safe mode with this kernel, and the upgrade wiped out the older version of the kernel.
I have googled for possible solutions, but nothing helpful is popping up. I am also running grub, and not grub2, but that is OK for this kernel according to
debian.org.
Any suggestions on how to proceed?
