| I'm having problems accessing a ZIP drive under FreeBSD-stable, using a
|1542 controller. 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
