Kernel panic during boot.
Thinkpad T440p with Haswell i5-4340m.
Worked fine in 12.1-RELEASE & 12.2-REKEASE.
Screenshot of panic to follow.
panic: vm_fault_lookup: fault on nofault entry, addr: 0xffffffe090b035000
cpuid = 3
time = 1

First line should read:
panic: vm_fault_lookup: fault on nofault entry, addr: 0xffffffe0090b035000
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"

Here is a patch that should fix this problem: https://reviews.freebsd.org/D31262
That works! Thank you.
