This should all work together. It sounds like it should all just work. Especially if HPUX works. But HPUX sometimes cripples the bus speed or *wideth* based on what PDC tells it. Perhaps you need to do the same. I really don't expect any issues with bus speed on differential SCSIs. Possibly a wide vs narrow bus issue (Chip thinks it's wide and the cabling is narrow). We see that on C3k still and I started (but didn't finish) the code to query PDC about Host SCSI ID, bus speed, and width. > Anyway, I'll take an known good disk with me tomorrow and try that with > a different internal cable.

It's a matter of getting the linux driver the right parameters then. grant
