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. > Hmm, so its not hanging on transmit, its on receive according to what > you are describing? Is that consistent? 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. -- Cheers, Chris Howells -- howells@kde.org Web: http://www.kde.org.uk, PGP ID: 0x33795A2C KDE/Qt Developer: http://www.kde.org
