Checked some logs. Looks when the error happens, the physical address are
very small. Its' between 20M - 30M.
So could you have a try to reserve the memory starting from 20M?
Add "memmap=10M\$20M" to your grub.cfg or edit in kernel parameters. so ath11k
can't allocate from these address.
Or you can try to reserve even larger memory starting from 20M.
That worked, booting with memmap=12M$20M resulted in the working wifi:

When I attempt to boot my 5.10rc2 kernel with that memmap option, my
machine immediately hangs. That said, it seems to have done something
bizarre, as immediately afterwards, if I remove that option and let
5.10 boot normally, it seems to boot and bring up the wifi adapter ok
(which didn't happen before). Now that I've managed to boot 5.10
twice, the first time after a couple of minutes my video started going
nuts and displaying all sorts of artifacts[1]. This time things seem
to be functioning nominally (wifi is online and the machine is
behaving properly). I may just never turn it off again :D.
Honestly, that FW sounds horribly flawed. :)
Would be interesting what happens when you boot back to 5.9 now ...
