Ok, per Doug's request I hacked up the driver to panic just before
scanning Chan. A. Here's what transpires:

aic7xxx: <Adaptec AHA-274X SCSI host adapter> at EISA 2
aic7xxx: BIOS enabled, IO Port 0x2c00, IRQ11 (level sensitive) Rev <= C
aic7xxx: Extended translation disabled.
aic7xxx: Twin Channel, A SCSI ID 7, B SCSI ID 7, 4/4 SCBs, Qfull 4, \
QMask 0x7
aic7xxx: Downloading sequencer code... 378 Instructions downloaded
scsi0: Adaptec AHA274X/284X/294X (EISA/VLB/PCI - Fast SCSI) 4.1/3.2
scsi: 1 host
Kernel panic <6>scsi0: Scanning Channel A for devices

scsi: aborting command due to timeout: pid0, scb0, channel 0, id0, lun0 \
0x00 00 00 00 00 00

aic7xxx: Abort called with no SCB for cmd.

I hope this helps, and do let me know if you want other things tried?
