Perfect. This is exactly the information needed.

The two successive samples you posted from /proc/interrupts show lots of system activity, but with the system timer stuck. Normally, the timer interrupt should increment 100 times per second, but your posting shows it sitting still with a count of 1236.. exactly as predicted, and now confirmed.

I'll release v223 (shortly) with the fix included (and the message removed, since they cannot happen with the fix in place). Please install, and report if the unit ever locks up again.

Cheers
