This trace doesn't make sense to me. A null EIP usually indicates
jumping through a NULL function pointer. There are no fptr derefs in
scsi_delete_timer. Also ahc_linux_run_complete_queue doesn't call
scsi_delete_timer.
Could you try to reproduce and get a more meaningful backtrace?
Thanks,
James

I'm pretty stumped as to what's going on with this. The stack is
moderately deep. It's also possible a fair fraction of the stuff is
garbage off the end of the stack and the real leaf routine is buried.
