I am, with some help from a small number of testers.
Currently, the driver is stable for all devices _except_
scanners. We can make it work with scanners, but it
is extremely slow. So slow that it is not useable.
I have not yet solved this problem.

Perhaps. Have you done any device driver debugging before ?
Do you understand the risks ? Be sure that you have a machine
available with nothing important on it.

Actually, what's happened is that the paride driver
detects the 90c26 chip. The registers in the chip have
entirely different functions in the IDE application and
the SCSI application, except for the bus reset bit. The
ISA device reset and the SCSI bus reset happen to be
controlled by the same bit in the same register. That's
why you see the light flash.
