Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I suspect I already know the answer, but just in case: I have 2x50Gb seagates attached to an AD29160. Initial tests suggested they were ok, but under loading they've started, fairly consistently, keeling over. They do this running at 80Mb/s, or if I tell the adaptec controller to take them down to 40Mb/s; I've swapped cables (but not terminators - LVD terminators aren't easy to track down). I've tried forcing termination on the controller as well as leaving it to auto-terminate. I'm running 4.0-RELEASE. Errors are many, on either disk, of the form SCB 0x67 - timed out while idle, SEQADDR == 0xc WARNING no command for scb 103 (cmdcmplt) no longer in timeout, status = 34b Issued Channel A Bus Reset. 2 SCBs aborted ahc_intr - referenced scb not valid during seqint 0x71 scb(103) and many variations on the above. I know (from archived messages) roughly what these mean in terms of the scsi states. Often they will eventually lead to a kernel panic. Would I be correct in thinking I have (most likely) a flakey terminator, cabling, or disks, or is there any known issue with the drivers for the adaptec 29160? All I've been able to find in archives suggests flakey hardware ... -patrick. [ off to find another terminator to test against ].
