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.
