Hi there,
I’ve recently experienced two kernel panics on 8.4-RELEASE (within 2 days of each other, and both around the same time of day oddly) with ZFS. Sorry no dump available, but panic below.
Any ideas where to start solving this? Will upgrading to 9 (or 10) solve it?
(Sorry for any errors, hand transcribed from a screenshot)
