The commonality seems to be listing or accessing portions of this file tree. Curiously enough it only seems to be isolated to that single portion of the filesystem tree. The zpool is also clean as far as errors go: > [16:11:03] tyler:freebsd git:(master*) $ zpool status zroot > pool: zroot > state: ONLINE > status: Some supported features are not enabled on the pool.

See zpool-features(7) for details. > scan: scrub repaired 0 in 0h18m with 0 errors on Fri Mar 28 11:55:03 > 2014 config: > > NAME STATE READ WRITE CKSUM > zroot ONLINE 0 0 0 > ada0p3.eli ONLINE 0 0 0 > > errors: No known data errors > [16:19:57] tyler:freebsd git:(master*) $ I'm not sure what other data would be useful here, I can consistently see the panic, but this data is highly personal, so I'm not sure how much of a "repro case" I can give folks. :( Cheers -- - R.
