The driver is still oops'ng on current scsi-misc-2.5, but I tried
linux-2.5 bk 2.5.69+ (change set 1.1095) and it did not oops after
multiple insmod/rmmod cycles.

I do not get consistent oops, but the one below occurs frequently on
rmmod. I will track it down more on my system and see if there are
changes between linux-2.5 and scsi-misc that would address what I am
seeing.

My configuration is 2 qla2300, IBM 2109 switch, IBM FASTt 200, 10 FC
JBOD disks.
