Problem solved, thanks to the rawhide patch from Richard Henderson ([EMAIL PROTECTED]) posted on Sunday. Performance is ~10megs/second both directions, using tulip, de4x5 or via-rhine. Using 2.4.4-ac15 it works fine. I'm now trying 2.4.5 Andrea, 2.4.5aa1 oopses just after probing the scsi

Hello Andrea, Jay, if the problem still exist in 2.4.5-pre6aa1 (please try the new kernel), then I will have tech op's check this on Tuesday (Monday is a US holiday). We should be able to duplicate this in the hardware lab and find the problem with a logic analyser. Best Regards, --George
