done it (not with Quantum drives, though) many times - transferring CD
images from my HP 6020i to a 4GB SCSI hard disk, both on the external
chain of a 2940.  On a K5-75 machine, no less.

I have *never* had a 2940 lock up on me unless there was a bad sector on
the hard drive or something went very south on the 2940 and it had to be
replaced (I had one 2940 go bad - Adaptec, unfortunately, claims that if
the ctrl-A menu works, the card isn't bad... but, the card is definitely
bad :) ).  I've burned all of PHT's CDs made in the last 2 years under
Linux using an HP burner on an AHA-2940 card.  I have all my servers but
one running a 2940 with SCSI disks (finally got all the Quantums out of
there - anyone ever heard of a Quantum Grand Prix?  They don't make them
anymore due to reliability problems, to which I can attest.)

i've never run a 2.1.x kernel though, so all my experiences are based on
1.2.x, 1.3.x, and 2.0.x kernels.
