Cc: trimmed to linux-kernel only, this looks like a kernel and/or
modules problem.

You have kernel module loader support compiled in. This automatically
loads modules as required. The cron job automatically unloads those
modules that are not in use.

scsi_io_completion is in scsi_lib, part of scsi_mod. Either scsi_mod
is not being reloaded when required or, more likely, it is still
present but is marked as deleted. Please reproduce and do "cat
/proc/modules". If scsi_mod is marked "(deleted)" then the problem is
that scsi_mod cleanup is not working. There are known bugs in scsi
clean up on 2.3.49, try 2.3.50.
