2.4.4 del_timer_sync oops in schedule_timeout

[Jacob Luna Lundberg]

This is 2.4.4 with the aic7xxx driver version 6.1.13 dropped in.
The oops got eaten by klogd, my apologies, but it seems sane even so.
I haven't tried newer -ac or -pre kernels so I'm sure it's probably
already fixed there but just in case it isn't...
