What problems exactly? I tried to deploy quite a hefty new news server
today, but after 5-15 minutes the sym53c8xx driver locked up (box still
alive, but no more interrupts from both SCSI controller channels).
(I just mailed Gerard Roudier about this).

Is that the driver locking up, or the on chip sequencer ? Would it
make sense that both channels (scsi0 & scsi1) stoped working ?
