Ok, interesting; so it's the --hard-disk-standby code that causes your disk to get restarted ... this means the following is likely:
- drive is downed by /sbin/reboot - drive comes back up for some reason - drive is downed by kernel Can you do the following for me: - switch to a console (alt-f1 or ctrl-alt-f1 within X) - run (as root) "telinit 1" That should (after a few seconds, you'll need to wait) give you a root, single-user shell. - run "echo 8 > /proc/sys/kernel/printk" - run "echo 1 > /proc/sys/vm/block_dump" You'll now start getting messages whenever the kernel needs the disk. (Test that with "touch /foo" or something if you like). - run "halt --debug --force --hard-disk-standby" Note where your disk spins down, and up, and see if you see can see what is causing the disk to be brought up again. You should see something like: PROCESS(PID): WRITE block NNN on YYY or maybe PROCESS(PID): dirtied inote NNN (FILENAME) on YYY If you could copy those, that'd be useful (don't worry about the timestamps) -- Hard disk stops and restarts on shut down https://launchpad.net/bugs/61763 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
