Do you get kernel panic or the system just freezes? I tried this on a freshly booted system, logged in, but did not start X, as you requested. When I plugged in the drive, after a little delay, I got the same "AutoSense failed" chatter. I then unplugged the drive and the system seemed happy -- no panic. I plugged the drive back in and tried to run 'dmesg', which hung. Wondering if I should have tried the dmesg before plugging the drive back in, I tried 'reboot', which also hung. Eventually some timeouts went off and the system tried to reboot, but hung while doing that. I had to power-cycle the machine to bring it back up. It had not properly umount-ed the file-systems, so fsck-ed them when restarted. I waited for that to complete and then repeated the experiment a little more carefully: - plugged in the drive, got the 'AutoSense failed'. I ran dmesg, which worked correctly. - unplugged the drive, ran dmesg, worked correctly. - plugged the drive back in, ran dmesg, which hung (something locked in the kernel?). I then unplugged the drive, which I hadn't done the first time, and dmesg completed. I was then able to reboot the system normally, no fsck-ing. /Don > > //Marcin > > _______________________________________________ > freebsd-usb@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-usb > To unsubscribe, send any mail to "freebsd-usb-unsubscribe@freebsd.org" >help
