[mythtv-users] X runs at 90-95%CPU

[Yan-Fa Li]

Wow.  Weirdness prevails.  There are a bunch of possible issues.  Are 
you sure your powersupply is up to snuff ?  What brand and size of PSU 
are you running ?  Since the problem occurs when you use the second RAM 
module, it could be because you're stressing out the 3.3V rail on the 
PSU and it's effectively browning out.

Any chance you can plug in a known good external psu into the board 
temporarily and run the test again ?
