           Summary: atrtc1: Warning: Couldn't map I/O.: system pauses,
                    then reboots
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any

framework 13 laptop (MSI Crosshair 18 HX AI A2XWGKG-012US)[1],[2]
CPU: Intel Core Ultra 9 Processor 275HX [3]
GPU: NVIDIA GeForce RTX 5070 Laptop GPU with NVIDIA Optimus supported [4]

booting from:
fbsd16 16.0-CURRENT FreeBSD 16.0-CURRENT #0: Thu Sep 25 03:43:37 UTC 2025

I'm currently unable to boot any of 13.5,14.n,15.n or 16 on this laptop.
On 13.5 it hangs on sc (syscons(4)?) connect...
and on all others, it's appears to be a timing problem:

Event timer "HPET" frequency 19200000Hz quality 350
Event timer "HPET1" freq...
...
Event timer "HPET7" freq...
atrtc1: <AT realtime clock> on acpi0
atrtc1: Warning: Couldn't map I/O.

and that's where it stops/reboots.

In all cases, it hangs for some 5 to 7 seconds and reboots.
This is a UEFI only laptop. I'm not sure where to start. I'd feel more
confident on where to go from here. But w/o dmesg.boot, pciconf, ... I'm
a bit short on data.

The laptop I'm writing this from is a framework 12 on 16 and since I have
src/ I can build a kernel/world with whatever kernel tweaks I need to make
this framework 13 laptop boot. I'll be glad to help in any way to make
FreeBSD work on these.

Thank you for all your time and consideration.
