Ah, tough luck. What if you attach an strace to the already stuck
process? Like strace -p pid. It's a long shot, but worth a try, I
suppose.

You could also try to use sysrq to output some useful information
about the stuck process. See Documentation/sysrq.txt for more
information. Gotta run, good luck!
