Your best bet is to use one of the following:
0) Use sysrq to investigate a bit:
https://www.kernel.org/doc/Documentation/sysrq.txt
1) Hook a serial console up if your system has one to another system
with a null modem cable and console=ttyS0,<baud> passed in to the
kernel at boot
2) Try netconsole if you don't have a serial console:
https://www.kernel.org/doc/Documentation/networking/netconsole.txt

I would recommend trying a newer kernel and see if your bug is fixed.
If it is you could bisect down to the commit that fixes it and let the
debian kernel maintainers know.

Good luck,

Brandon
