No WiFi after resume on Thinkpad X1 Extreme G2

[mmspl]

A follow-up to https://forums.freebsd.org/threads/resume-on-thinkpad-x1-extreme-g2-ends-in-black-screen.88162/, so I'll create a new thread.

I am on 13.1-RELEASE

I can now resume the computer from sleep. However, the WiFi is down - I have AX200.

In dmesg I see that

Timeout waiting for hardware access

and then the state of the registers for iwifi.

I tried to service netif restart, but I get

drm_modeset_is_locked

at drm-510-mod.

If I do the restart when WiFi works, I just get

panic: general protection fault

but if I do it when the WiFi is already down, all I get is a flood of frm_modeset_is_locked - no panic, just a locked computer.

It looks like it's not supported yet:

There is supend/resume code in the source files though:

To make sure you could contact the developer or send a mail on freebsd-wireless mailing list (to which most likely the same developer will respond), see "Contact" section in the wiki.
