Chapter 8. Known Bugs And Assumptions

Interrupt Locking

The locking in the driver is done via the global cli/sti lock. This makes for relatively poor SMP performance. Switching this to use a per device spin lock would probably materially improve performance.

Occasional Failures

We have reports of occasional failures when run for very long periods of time and the driver starts to receive junk frames. At the moment the cause of this is not clear.
