Most people who report this panic have hardware problems such as flaky memory.
For bugs matching the following conditions: - Status == In Progress - Assignee == "bugs@FreeBSD.org" - Last Modified Year <= 2017 Do - Set Status to "Open"
The PTE code has changed drastically since this was reported, and it was likely a hardware fault in the first place. Closing unless we get more information.
