As soon as I generate some significant disk activity, |the following happens: | |Jun 30 14:40:22 misery /kernel: sd0(aha0:5:0): timed out |Jun 30 14:40:22 misery /kernel: adapter not taking commands.. frozen?! |Jun 30 14:40:22 misery /kernel: Debugger("aha1542") called. |Jun 30 14:40:23 misery /kernel: AGAIN |Jun 30 14:40:23 misery /kernel: aha0: MBO 02 and not 00 (free) I have an old, flakey SCSI-1 connor drive hooked to a 1542 that generates these exact error messages. I trigger or test it by dumping the filesystem on the affected drive. I believe that the drive's controller freezes when it hits an unrecoverable error in the media --- the error messages go away when I swap it out for an identical drive. Rich
