Thanks should go to the Foundation for iwlwifi.

Great!  And thanks a lot for testing things out!

Yeah doing this on Laptops directly is a pain these days.

Do you actually power cycle the box (turn it off, wait a few seconds
and turn it back on) or do you just reboot?  For some
re-initialisation that makes a difference these days sadly.

In the below dmesg the firmware crashed during boot and everything
after is a follow-up error (that shouldn't be related to
power-cycling).  If I remmeber the magic numbers correctly from the top
of my head the error seems to be due to a scan command.

The real problem is in the last line of these:

What seems to happen is that we go through a full auth/assoc cycle to
running but the firmware/driver decide for some reason they haven't
heard a beacon and tear us down again and then things go south

I am currently still trying to get fixes out and committed for other
things which may also help this.  Can you keep an eye on notifications
here and then update and try again.

I'll be happy to spend more time on this if the next batch of changes
doesn't help this particular issue.

Happy weekend,
