I would say you have a timer issue, or perhaps the same issue with 
SD-card as Andreas. Have you tried turning off the options I said Adreas 
to disable yesterday? (dynamic ticks and high res timers)?

When the system is stuck, do you still see the timer interrupt count 
incrementing in /proc/interrupts? Same question for the MMC interrupts.

Since you are the one having the issue, you will have to do the 
investigation. If you do not do that, do not expect the issue to 
magically go away.

I work for the I-pipe patch for the ARM architecture on my free time. 
So, I do things when I want to, without any deadline, and certainly not 
under pressure.
