--- Comment #1 from emz at norma.perm.ru ---
I'm getting this periodically too. The problem first appeared on 11.x, and
persists on 12.x.
I was able to take the crashdump by invoking the panic manually, compressed
crashdump anlong with the kernel binaries is available at
http://82.194.234.25/crash/
Please let me know if I can help with debugging this in any possible way.
zfs-related processlist part at the moment of lockup:
