First thing I'd do is get my hands on ksymoops and look at the callstack.

Check out...

http://www.kernel.org/pub/linux/utils/kernel/ksymoops/v2.4/

>From my past experience, seems to me that I have had a similar oops
when the driver code that I have been debugging usually is stuck in a
loop at interrupt time and your missing interrupts.

Or better yet, your just plain crashing at interrupt time.  It sounds
like this is pretty easy to reproduce so follow the readme on
ksymoops.

Hope that helps.
