Add to /etc/sysctl.conf:

debug.kdb.break_to_debugger=1

Use such debugging kernel to drop to the debugger when deadlock occurs
using Ctr-Alt-ESC and type "call doadump", you should get crashdump anyway.
Then use "reboot" or just power cycle to get crashdump stored to /var/crash.

Then fill a PR and reply with the number.
