Public bug reported: Immediately after login watchdog soft-lock cpu (x) occurs. Attempted different desktop environment, reinstalling and reconfiguring lightdm, logging in from shell and updating. Nothing that I've tried has able to get me logged into a desktop environment since I get a CPU lockup before then. Attempting to shutdown from shell also results in unexpected behavior. 'sudo shutdown -a now' results in a black screen and unresponsive keyboard, I'm forced to hardboot.
