A normal unprivileged userland application should not be able to bring
down the kernel. Do you use any additional drivers, e.g. for the serial
bus? If so, it is a good idea to enable kernel crash dumps, and send it to
your driver developers to analyze the bug.
Other than that, you could (in no particular order):
- Let syslog send messages to some remote site.
- As others suggested, use remote X or a serial console to be able to
track important messages.
- 'systrace -f' the X11 program, and redirect the output somewhere safe,
to see the last actions that were performed by the program.
With kind regards,
