The only thing that works for me is to actually power off my machine for 
about 10 seconds.  A warm reboot won't work; you actually need to cycle 

I recently upgraded to the latest firmware, but right after that my 
power supply died, so until I get a new one I won't know if the newer 
firmware fixed the problem :-(
