My computer would occasionally freeze when I shutdown or rebooted the computer for whatever reason. As of late, every time I shutdown or restart it freezes and now it's becoming a PITA.

I have no idea how to debug this and really need some help :(.

maybe you could do as @waltinator said, then edit your entry a show the log. – maniat1k Dec 3 '11 at 13:53

If I were debugging this, I would cause the event (freeze when shutdown/reboot), boot into a recovery mode (do the least recovery possible), and do an ls -lrt /var/log. This would tell me which log files have been modified recently. Any messages having to do with the problem would be in these files.
