You might try running 2.1-STABLE : instead and see if that makes the problem go away. hi again. I'm SURE its not a config or termination thing - linux and OS/2 (naturally DOS/win too) work just fine. I've just recompiled the kernel to 2.1-stable, and it seems to have helped a lot. Previously, the machine actually locked and messed the filesystem....now...well...the below is what happened right at the end of my first test tar (20Megs) to the tape. It also happened immediately after I tried to restore too... sd1(ahc0:1:0):timed out in command phase, SCSISIGI==0x84 st0(ahc0:6:0):asserted ATN - device reset in message buffer st0(ahc0:6:0):timed out in command phase, SCSISIGI==0x94 ahc0: Issued Channel A Bus Reset #1, 3SCBs aborted sd1(ahc0:1:0):UNIT ATTENTION asc:29,0 sd1(ahc0:1:0):Power on reset, or bus device reset occurred field replaceable unit: 29 ,retries:3 after that, the machine seems to recover (thankfully!) - the SCSI bus doesnt lock up like it did before. so - looks like the slow tape doesn't relinquish the bus quick enough, and clobbers a command intended for the disk..?????? ideas anyone? the tar TO the tape was so close... it must be something pretty small - as I said, 2.1-stable is a radical improvement. the 2742AT is an EISA controller. I also have a DX4/100 overdrive in a 33MHz motherboard. if anyone wants any more info to help with a possible solution, feel free to mail. thanks again --Bill Nutt bill@winu.fa.umist.ac.uk
