I have just pushed fairly recent iwlwifi driver and firmware updates
into main a few minutes ago.   I hope I got all bits out of my dev
branch correctly and will monitor the builds.

 	062103fc93c3 iwlwifi: update firmware
 	51152e5e6150 iwlwifi: enhance debug information
 	d9836fb4b938 iwlwifi: update from iwlwifi-next

I hope some people will give it a try in main before I'll MFC it to
stable/13 next week.  This should not make much of a difference to
what you have had so far.

!!! Please note:  this does NOT yet fix most of the linuxkpi_sta_X_to_Y
errors followed by firmware crashes or panics yet though they should
avoid at least one of the causes which triggered them. !!!

I am still trying to get fixes for these in the next days;  I have a
partial fix dealing with some of the state changes which helps to hold
up longer.

If you see any other (new) errors please let me know.

Lots of health,
