Description

When running a reroot on my firewall (Dell R220) it starts to stop services just fine then kernel panics and does a warm reboot. This has not been experienced prior to upgrading to v23.05 ( I upgraded from community 2.6.0 ).

Main panicis:
Panic String: vm_fault_lookup: fault on nofault entry, addr: 0xffffffff836cf000

The crash looks like it could potentially be a problem with the filesystem or disk. While there is a possibility it's a FreeBSD/OS bug, more likely you need to run several rounds of fsck on the disk (or wipe/reload) to ensure the filesystem is in good shape.

Since this bug is triggered by unloading the zfs module incorrectly on systems that do not require it also see: https://redmine.pfsense.org/issues/13183
