I am able to solve the SCSI command timeout problem by adding a code
to check the hardware register busy bit continuously, in
kagen2_ep_queue():
do {
read_hardware_register_busy_bit
} while (hardware_is_busy)
however, it causes the linux prompt to be non-responsive because the
checking hardware register code is run continuously. If i add a
schedule() to the do-while loop, the kagen2_ep_queue() will not be
continued. How to go about fixing this dilemma?
thanks,
victor
