While running my http://vanheusden.com/pyk/ script (which randomly
inserts and removes modules), the module 'ide_pci_generic' got unloaded
while filesystems were mounted that used that module. Of course the
system crashed but I think it should not be possible to unload
modules when resources it serves are still in use.

Hang on: it is not ide_pci_generic causing the filesystem errors. Still
investigating.

Odd, these modules were unloaded but if I unload them "by hand", the system
keeps running without any failures.

-battery
-button
-container
-dm_mirror
-dm_snapshot
-fan
-floppy
