--- Comment #2 from Mike Cloaked mike.cloaked@gmail.com --- After a normal looking bootup and working with a normal kde session, I logged out of kde, and used the kdm greeter screen to request the system to reboot. It seemed to exit from X but left the system hanging with a VT visible but it had not rebooted.
At this point I captured the dmesg and journal files which I will now attach.
