I am going to reinstall the fglrx driver and try and debug these messages when they come up according to this wiki page https://wiki.ubuntu.com/DebuggingKernelOops.
** Description changed: Ocasionally, when I shut down, I am sent to the plymouth splash screen as usual, however the ubuntu logo and the progress dots are static - they are not moving. This has been happening more recently over the past week. The hard drive LED on my case is not lit up at all when this happens. EDIT: More info has been uncovered, after quietsplash was turned off at shutdown and boot, these logs were in my view: """ BUG: Unable to handle kernel paging request at ffffc900117da000 Oops: 000 [#1] SMP PID comm: chromium-browser RIP [<ffffffff81066cff>] warn_slowpath_common (A LOT of text) At /build/buildd/linux-3.2.0/kernel/watchdog.c:241 watchdog_overflow_callback+0x9a/0xc0 () Watchdog detected hard lockup on cpu 0 modules linked in: nls_utf 8 ... ... etc etc -----[end snippet]----- """ + (This is not exact) I also saw something about the chromium-browser and the fglrx driver (Although it may be to do with dependencies or something as I had just purged it .). These bugs appear to by synonymous with my problem http://lkml.indiana.edu/hypermail/linux/kernel/1107.1/02053.html and https://bugzilla.redhat.com/show_bug.cgi?id=822287. This is the code that is supposed to trigger it http://lxr.free- electrons.com/source/kernel/watchdog.c#L214.
