--- Comment #19 from Mateusz Guzik <mjg at FreeBSD.org> ---
can you reproduce with this crude debug patch in?

https://people.freebsd.org/~mjg/cache-debug.diff

if anything goes wrong it will print to dmesg lines starting with
cache_enter_time

there is some fishy code which may or may not be buggy in a way which gives
this problem. if you run into the failure without the message showing up, i
don't know what this can be
