Now I'll go out on a limb and guess: our Buslogic support is broken. Someone has to provide an alternate SCSI board to these customers until it is fixed. In spite of what Rodney said earlier, I like Buslogic because they have been extremely helpful to me in the past, and so the help they gave me cancels the four hour phone wait Rodney had, and FreeBSD customers should give them another chance and let's not put them on our "Don't buy this stuff" list (It wasn't that long ago that I regularly saw "buy Buslogic" postings). Is anyone in a position to get a known working PCI SCSI board to sef? This is a FreeBSD support challenge and I'd like to see us rise to it.
