two crash back traces

I got frequent crashes (about 1 to 3 per day) of Freebsd 14 running on a NUC6CAYB.
either page faults or double faults. Hardware has disable bt, no attached keyboard, monitor, mouse.

All crashes are related to 
/usr/src/sys/amd64/include/pcpu_aux.h:57

Please find attached two crash descriptions.

Are the crashes related to acpi problems?

Same problem here, FreeBSD14.0 on a NUC6CAYB.
Running without Screen/KB/Mouse, disappears from Network after a short while. 
Hint: Used Debian before, it also crashed until: Booting with legacy BIOS, plus “acpi=off” as boot parameter. Then it was stable for month w/o reboot.
Any ideas?

Does a different timecounter hardware make any differences?

FYI, the following is from my VM.
```
# sysctl -n kern.timecounter.choice
TSC-low(800) i8254(0) ACPI-fast(900) HPET(950) kvmclock(975) dummy(-1000000)

# sysctl -n kern.timecounter.hardware=HPET
kvmclock -> HPET
```
