More Adaptec 2940 Woes

[Michael.Hoffhines@mccada.mauicc.Hawaii.Edu]

I'm trying to install Debian R6 on a PCI (Triton chipset) machine with
the Adaptec AHA-2940 SCSI adaptor that has caused so much grief. Anyway, I
have the recent boot disks that were supposed to support this adaptor and,
indeed, the boot-up sequence appears to recognize the card initially. After
the text below appears, the system dies. Any ideas?

Here's the console output:
