I observed the same behaviour when one disk went down, corrupting some data
on the second at the same time. The 'good' disk didn't mount /var anymore.
The key to what was going on, was monitoring the boot process with a serial
null modem cable (115200,n,8,1) and see the system report a lot of 'file not
found's' just before rebooting. The solution in this case was mounting the
'good' disk in a SuSE 8.2 system (it has xfs support in the kernel by
default) and run xfs_repair -L /dev/hdc2
