I just (ie. 5 minutes ago) solved a problem where a LavaLink
Quatro-pci 4-port cards locked up a NetBSD 1.5E machine hard whenever
the first port was accessed. It turned out to be a flapping CTS line
on the card itself which caused the interrupt handler to never exit,
since it loops around to the beginning if there is another interrupt
pending. The 'solution' was to plug a cable (yes, just a cable) into
the port. Now the card works - how reliable I don't know yet...
