Somebody in the thread at some point said:

I'm working on adding the andy-2.6.26 stuff to andy-tracking right now
and seeing the same.
Previously (some weeks ago) on tracking there was trouble with hdq that
I put down to PWM init affecting the timer used for FIQ generation. I
moved the FIQ timer to another PWM unit and the problems went away.
Since then FIQ is trashed by later changes upstream I am trying to
figure out now.
Anyway I would dump the PWM-related registers from CPU on 2.6.24 or
2.6.26 and current tracking and compare them, it seems it might give a clue.
