I've nailed it down. It is a stack buffer overflow in the
nvidia-driver. I've submitted patch to port maintainer.

P.S. Panic isn't reproducible with INVARIANTS :(

More investigation. AFAIU, we can't come to this point
if __mtx_lock_sleep() passed a NULL ts. So ts wasn't NULL
before call to propagate_priority(). The turnstile_wait()
saves ts on td:
738:td->td_blocked = ts;
So I can obtain it:
(kgdb) fr 11
#11 0x805206b2 in turnstile_wait
Hello,
