This was caused by the option CONFIG_DEBUG_PAGEALLOC.

I'm currently using kernel on a P4 3.2 GHz system with 
hyperthreading, but my problems with this go back a few kernel versions.

I'd get mythbackend crashes quite regularly when using both tuner 
cards.  Occasionally, it would crash if I was recording only one 
program, and once it crashed when it was just sitting idle (no 
recordings in process).
All of the backtraces showed one or two threads with a corrupt stack.  
Everything's run fine since I changed the above parameter last week.

Hope this helps,
