--- Comment #7 from Bert JW Regeer <xistence@0x58.com> ---
Alright, figured out the issue with the firmware not loading is due to me
trying to pass it through to a VM.

So, from the host, with the patch applied, the system panics as soon as I d=
o:

kenv dev.iwm.0.debug=3D0x00080000
cd /usr/obj/usr/src/amd64.amd64/sys/GENERIC/modules/usr/src/sys/modules/iwm
devctl detach iwm0
kldunload if_iwm
kldload ./if_iwm.ko

Picture of output with stack trace:

I would rather it not panic, and instead just unload the driver, but here we
are.

Panic message transcribed:

panic: ieee80211_get_ratetable: no rate table for channel; freq 0 flags 0x0
