In that case, you may be stuck with debugging the debugging process.
adding printfs to the perimeter (with a serial console), and gradually
worming your way in.  Not all printfs happen in some cases, so there
may be some abiguity that may drive you nuts...

Chances are the kernel/debugger is restoring state bogusly, and that
we're jumping to that bogus state, causing the reset (most likely in
kernel mode).
