--- Comment #5 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
There is a generic problem in the LLE code (IPv4 and IPv6) that it cannot s=
leep
to drain the timers. In case an active timer is detected after callout_stop=
(),
then the LL entry should be put on a taskqueue and callout_drain() _must_ be
used for sane operation.
