I got this oops on a 2.5.44 system (single CPU, preempt enabled, as was
slab debugging) when unmounting a full ramfs partition.
This is 100% reproduceable for me; mount ramfs, run dbench in that mount
point, the system will run out of ram as dbench fills up the ramfs
partition, and kernel will OOM kill dbench and your shell. Login again,
and unmount the ramfs partition, oops.
VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice
day...
