First line should read:
panic: vm_fault_lookup: fault on nofault entry, addr: 0xffffffe0090b035000
Comment 3 unitrunker 2021-07-20 21:41:35 UTC 
I have a poor work-around (but better than nothing).
Disconnect AC power and reboot.
On the third try - without AC power - the boot usually completes.
Everything seems to work once I get past this stage.

The CPU defaults 2.9 Ghz when booted on AC power and 0.8 Ghz when booting from battery power.

So far I've not gotten a crash dump. I do have a swap partition and dumpon(8) verifies this. rc.conf has dumpdev="AUTO"
