--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
- Any chance you can get a full vmcore for this panic?  The AES code in
question hasn't changed in a long time, so this is more likely a bug in
opencrypto or GELI and so will be harder to debug.
- Are you able to confirm whether this happens in 13.0?
- Are you able to test kernel patches?  Based on the fault address I'm
wondering a bit if this is related to handling of unmapped I/O in GELI, which
was added in 13 and doesn't seem to be present in 12.  We don't currently have
a chicken switch to disable it, so a patch would be needed to test that theory.
