And there are these, which you didn't mention: > ad1: FAILURE - SET_MULTI status=3D51<READY,DSC,ERROR> error=3D4<ABORTED> > ad12: FAILURE - SET_MULTI status=3D51<READY,DSC,ERROR> error=3D4<ABORTED> (No, I don't know what that means, sorry.) > ad18: 1430799MB <Seagate ST31500341AS CC1H> at ata9-master SATA300 > ad20: 1430799MB <Seagate ST31500341AS SD1A> at ata10-master SATA300 How old is the SD1A disk? As you may know, Seagate had various troubles with the .11 firmware. I have some of the ST31500341AS CC1H and mine are new enough that they are supposed to be ok. > Therefore, I am inclined to think the motherboard/memory (a "TYAN > Thunder K8WE S2895") would be at fault here, I have been told that Tyan does a good job with memory, although even assuming that's true it could still be a memory problem. My Tyan board has a memory scrubbing feature that can be turned on in firmware, but I've never tried it. Also, you could try rotating the SIMMs and see if anything changes. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[email protected]"
