Linux 1.3.66: Problem with SCSI bus scan

I upgraded my Linux kernel to 1.3.66, followed by an upgrade to 1.3.68.
Since then, I am getting the following occasionally when the SCSI bus
is scanned (although sometimes the error happens on SCSI id 6):

scsi : aborting command due to timeout : pid 7, scsi0, channel 0, id 4, lun 0 Test Unit Ready 00 00 00 00 00
aic7xxx: (aic7xxx_isr) BRKADRINT error(0x1):
Illegal Host Access
Kernel panic: aic7xxx: (aic7xxx_isr) BRKADRINT, error(0x1) seqaddr(0x0)

In swapper task - not syncing

I never had this problem with 1.3.57 (which I was running before the
upgrade to 1.3.66). Here's what a successful scan looks like:
