Public bug reported:
Happened right after a YouTube video of music finished. mouse and
keyboard locked up but system monitor applet kept running showing full
usage of all four cpu cores. tried to log on remotely but this was very
slow. used htop to see what was using cpu but it showed only three cores
active with boinc work units as usual conflicting with the system
monitor applet. eventually htop stopped working. could not find excess
cpu usage with top either. eventually the system monitor applet showed
only 50% cpu usage with lots of io waiting. eventually did soft reset.
cpu is overclocked but has run stable with heavy boinc usage for weeks.
