We had at least 4 crashes related to this bug (all within 2 months). Attached the messages of the latest two panics.
It's a DB server running postgres and a linux software raid10 setup for storage. On all occasions the machine had a higher load than normal ~20 - 30 (normally ~15), on the latest crash there was also a raid rebuild in the background.
