--- Comment #10 from Alexandre Kovalenko <bsd.gaijin at gmail.com> ---
I am seeing this (or similar) behavior on r333641 with sys/dev/vt rolled back
to r329305 (could not get console to work without the latter). I have dropped
into DDB and spa_namespace_lock is held by zfsd thread. I will be posting
procstat output and pictures of the backtrace shortly. Unfortunately, I do not
have serial console, so the pictures are all I got. I have induced panic from
DDB, so I have a dump as well. I can upload it somewhere or make it available
for download if it is of any value.
