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
- plugged in the drive, got the 'AutoSense failed'. I ran dmesg, which
- 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.
