Comment 15 for bug 338083

Colin, I wouldn't expect to see anything interesting in your log since it is working for you. It would be helpful for comparison to others though.

To get the log, you can try this:
do a reboot, and when your system reboots into the refit screen, turn it off (there is a menu item for shutdown here).
then put in a linux liveCD and boot from that.
mount your filesystem and make a copy of /mounted/path/var/log/messages
That should get you a log that is untouched after shutdown that you can attach here.

Then if someone else, who cannot reboot would try, then use the livecd as above to get their log file, they can be compared.
