Subject[qlogicisp.c PROBLEM 2.5] OOPS: "Unable to handle kernel paging request ..."
Hey, Jason and Bryon!

Got this one last night - it is def. reproducible. Vanilla 2.5.32.

Haven't got time to look into this myself until tonight, so I thought
I should let you guys know.

Anyone on lkml with comments ? I don`t get this OOPS with 2.4.19, and
the changes from qlogicisp.c in 2.4.19 to qlogicisp.c in 2.5.32 look
minimal. Only cli -> spinlock and io_request_lock -> host->host_lock
as far as I can see from a quick glance.
