Load test is this simple "cd /uu ; dump 0buf 126 - /w | restore xbf 126 -" between two partitions. First motherboard we tried was Intel PPro 200Mhz (FX440 based I think/Natoma?). Second one is newer 633MHz Celeron system but I don't know manufacturer. > One question - I assume you're not seeing any read error diagnostics from > the Mylex driver (other than the disk errors?) > Sometimes we have got more those scsi errors before fs panic.
