DAT's & Asus P2B-DS Problems

I posted a while ago about SCSI timeouts and lockup problems when using
a Sony SDT-9000 DAT and a couple of Seagate 39102LW's on an Asus P2B-DS
motherboard.
Fortunately, the ASUS Adaptec BIOS thingy lets you turn off Wide & Sync
negotiation for a given device so I played with that.
Having turned down the DAT to Async, turned off disconnects and Wide
negotiation, a test system has been dd'ing 9Gb of data onto the DAT for
7 days now without a single error showing up. Prior to those changes it
wouldn't last more than a few hours.
This is using aic7xxx 5.1.11/Linux 2.0.36 - using 5.1.6 the machine
blows itself away with a complete lockup (no console messages), both HD
lights on and, probably because of the lock, the ext2fs severely
damaged.
I know that others are having similar problems so there's one way round
it if not a solution per se.
I'll start trying to isolate which config option makes the critical
difference unless Doug wants me to try anything else?
