Kenneth D. Merry once stated: => I have this flaky SCSI CD, which works sometimes :) When it fails, I => see something like the following popping up: => => Creating DISK cd0 => (cd0:ncr1:0:6:0): got CAM status 0x4a => (cd0:ncr1:0:6:0): fatal error, failed to attach to device => (cd0:ncr1:0:6:0): lost device => (cd0:ncr1:0:6:0): removing device entry = =That is caused by a selection timeout. There's not a whole lot we can =do about that. I think I found it. I increased the SCSI_DELAY to 9 seconds and the drive seems happier now. I also switched to the new sym driver for my NCR-53C875. But this was not my question :) This was: => Under 3.4, if I was to try to mount a CD in this drive, when it was => in the bad mood, I'd simply get an error. Now, with 4.0 the thing => panics :( = =That's not good. In order to find the problem, we'll need a little more =information. Take a look at the handbook section on kernel debugging: = =http://www.freebsd.org/handbook/kerneldebug.html I'd love to do this, but it I don't have the time right now. I was hoping, someone who knows the code in question will be able to fix things quickly. It bites me when I attempt to use a device that was created, but then removed... -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
