Last night I installed 2.4.1-ac4 remotely on two machines that had been
running -ac3. Neither was essential to production so I rebooted
remotely to try it. One of them works fine. The other hangs at boot
with an interrupt synch problem (sorry, but I'm away from the office and
have only sketchy secondhand info; will reproduce Friday and supply
details if needed). The contents of /proc/scsi/aic7xxx/0 follow for
each (the machine that failed has been rebooted with -ac3).

No failure, 2.4.1-ac4 running:
