Subject: Error using the buffer cache

I've written a module that acts as a cache for fixed size objects but I
get a soft lockup trying to use the buffer cache.

I've attached the module that reproduces the error. You need to supply the
module with a block device, i.e.
insmod disk_cache.ko devname="/dev/hda2".
