This is a buggy expiry handler but it gets triggered as a result of
earlier OOPS:

Apr  9 23:30:01 vennen Call Trace:
Apr  9 23:30:01 vennen [] _spin_lock+0x16/0x90
Apr  9 23:30:01 vennen [] _spin_unlock+0xd/0x30

which doesn't seem to be related to IDE in any way.

It would be useful if you pinpoint issue further to a specific kernel version.
