hah, funny you should ask this right now. i have some really obscure
problems with the chip on my system together with open/netBSD. both
the sonic driver and the scsi driver works without problem if they
run alone. but together the scsi chip does some funny things. after
sending out a 6 byte cdb it interrupts with a message in (the disk
wants to disconnect) and the transfer counter = 0 but the fifo count
equal to 1. i don't get it. it should not be possible..
if you get any info, especially on chip bugs, im interested..
btw, nfs file read 829kb/sec.. :-)
