By the way, I think I found a kernel commit that should fix this issue:

If built with symbols, after it has gotten into the CPU busy-loop, use gdb
to attach to it, ala:
gdb
Ex:
gdb /usr/local/sbin/bird6 `ps -C bird6 -o pid=`
then "bt for a stack trace, possibly showing where stuck.

Hi,
We are experiencing regular "freezes" of bird6 on a BGP router. When this
happens, bird6 maxes out a CPU for several minutes. If a command is run
in birdc6 during such a freeze, the command hangs, and the result is only
returned when birdc6 has stopped using the CPU. Note that this also
