The systems do have the same motherboards and processors -- Asus A7V8X-X
and a Duron 1800. The other components differ slightly, e.g. one has a
SCSI card and tape drive and more RAM, but there isn't a vast difference.
I believe they both have the most recent BIOSes.

Oh yes sorry, should have clarified that. Correct, it hangs on receive,
consistently -- never ever on transmit. Though the conditions to cause it
to hang on rx are sadly somewhat unpredictable. I haven't seen the problem
really since before Christmas until recently when I've seen it quite a
lot. But then again I am transferring more data around at the moment due
to trying to recover from a hard disk failure in the 6.1-pre machine.
