Sounds like it might be an issue with the physical memory or
the timings. It could also be related to the idle loop not
restoring something right for deeper idle states that corrupts
the memory. And that's why it would seem to appear while waking
to a timer.
Maybe disable PM and run memtester to see if that runs reliably?

Tony
