When things get this bad, I hook up the serial console and insert a few 
widely spaced printk()'s into the suspect functions. Then I do a binary 
search until I pinpoint the exact point of failure. This works as long 
as something doesn't kill the system before the data can get out of the 
serial port. It usually gets you fairly close to the problem line, in 
any case.

 From my experience, I would be very suspicious of something going very 
wrong in your interrupt handler.
