What you are seeing here may be related to a recent regression that has now been fixed in the most recent release candidates for 9.1.21 and 9.2.10.

The expected result of the bug that has now been fixed in the release candidate would be a page fault, and we can see that in your logs:

> BUG: unable to handle page fault for address: 0000100000000008

The final releases with the fix are expected next week, but if this is the issue you may benefit from updating to the release candidate now.
