Well, a bisection definitely should help, but needs a lot of time in
your case.

Yes. compile, test, crash, walk out to the other building to press
reset, lather, rinse, repeat.

I need a reset button on the end of a 50M wire, or a hardware watchdog!

Something many of us don't realize is that nearly all Intel chipsets
have a built-in hardware watchdog timer.  This includes chipset for
consumer desktop boards as well as the big iron server stuff.

It's the "i8xx_tco" driver in the kernel enables use of them:

    modprobe i8xx_tco
