freebsd/sys/dev/aac/aac_debug.c
Justin T. Gibbs da4c1ce305 This is an MFC candidate.
Add the AAC_DEBUG option to enable debugging in the aac driver.

Correct a race condition in the interrupt handler where the
controller may queue a fib to a response queue after the driver
has serviced the queue but before the interrupt is cleared.
This could leave a completed fib stranded in the response queue
unless another I/O completed and generated another interrupt.
