This cannot be the solution. I have PPP performance problems and others
have SLIP etc etc problems on systems WITHOUT SCSI!
Thereust be another reason for the Interrupt Latency problem.
The point was not that it fixes the interrupt latency problem; it obviously
could not. What it does fix is at least some cases where a SCSI timeout is
signaled inappropriately.
