There is also an alt-sysreq key to remove all realtime
priority from all processes. Might be handy before a reboot
to see if it brings the system back. I'm pretty sure
it's alt-sysreq-N. The downside is it takes realtime priority
away from some kernel threads, though my experience is that
everything continues to work. YMMV, buyer beware, etc
