Which BIOS do you have?  I have 1.2.5.

I'm currently running 5.13 with a patch that reverted 
3579994476b65cb5e272ff0f720a1fd31322e53f.  I needed to do that or the 
5.13 kernel wouldn't connect to my access point because the firmware 
crashed.  (I got that pointer from 
https://bugzilla.kernel.org/show_bug.cgi?id=212059.)  With 357999 
reverted, everything works well.

I still have the memmap=20M$12M kernel argument set from the old qca 
bringup branch days.  Do you also use that?
