I've hit this and can reproduce it.  The SCAN_CFG_CMD is a red herring though
as they currently send some details to the firmware regularly from a work job;
I disabled it locally and now I see the less regular statistics command, which
I can confirm logging hardware comands.

This is the other interesting information;  though for me it's an AX210 and
slightly different.

THere I see things like:
 	iwlwifi0: Queue 2 is stuck 27854 28080 
before the firmware dump.
The numbers are the read and write indexes.

I need to go and see if we have a PR for this somewhere open as well
still.  We clearly had a lot omre reports years ago (see e674ddec0b41).

It'll likely be a few days but keep an eye on the commits mentioning
something like this.
