I have a 2940 connected to (among other things) a QUPD1800S.  During
extended periods of heavy read activity (ie backups) the device and/or
card will eventually hang, leaving the machine hung (there's a swap
partition on that disk).  The tape drive is on another SCSI controller,
so it's not the problem.  I have had varying success avoiding the problem
by running backups from a vt while the machine is otherwise idle, but
sometimes it hangs anyway.

After the hang the 2940 access light is on solid, as is the light on
the drive.  I have upgraded to latest greatest drivers several times,
since each has held the promise of more and smarter bus reset code, to
no avail.  I don't have another similar drive to experiment with, but
on my AHA1542Cf this same drive had no problems.
