After update to 12 I can't suspend any more on ThinkPad T430

It used to work with 11-STABLE.
Now the network (em0) will not come up again. What can I do to restart it?

Same here on 12-RELEASE-p2, although do not have experience with 11-STABLE, as I just got this Thinkpad.

Also when I hit the Fn key it goes to sleep (I am not touching other keys like F4). I have enabled acpi_ibm and acpi_video (I do not know if this is still valid?). Also this model has Optimus, but I disabled it in the BIOS and using the discrete graphics NVIDIA at the moment.
 
I have a disabled NVidia, too. But I didn't load the acpi_ modules.

The effect of acpi_video is that I can't regulate brightness any more. So another reboot ...

The Fn-only problem I don't have

(FreeBSD 12.0-STABLE r342641 GENERIC amd64)
 
Suspend works as expected in my T430 with 12.0-RELEASE.
I have acpi_ibm.ko loaded and use acpiconf -s 3 to suspend.
I cannot check em0 right now, but wlan0 perfectly works after resume.
No Fn-key problem, however, I use it to wake the laptop when it sleeps with open lid.
 
This time it worked. ifconfig em0 down, up, media auto etc. brought it up again :)

... next time not :(

Any ideas, as the same happens on T580 - em0 us in a status no carrier after a resume and the LAN port is off as far as the switch is concerned
