 Assuming mythbackend was using 100% CPU when the log was captured it
 appears that the system was busy collecting EIT. It doesn't look like any
 expensive fixup was being used so I think plain old EIT collection may
 just be stressing your system.

 Are you using an Atom or ARM processor?

 Since it's nothing really obvious the only way we can really figure this
 out is if you use oprofile to find the hot-spots, but that isn't really a
 task I can expect of you unless you are a programmer familiar with
 optimization so I'm going to tag this as unverified for now. Again, it may
 just be that the EIT rate is high enough that it would be expected to
 saturate a CPU.
