I have done 5 boots of pristine 5.10-rc2 with page_alloc.shuffle=1. Out of those: 1st, 2nd, 4th and 5th resulted in 
working ath11k driver, logs were the same as with the commit 7fef431be9c9ac255838a9578331567b9dba4477 reverted. The 3rd 
one failed, but in a different way, I just had no output from the driver after initialization lines:

I had this before and usually it was fixed after rebooting into Windows and back. This time I just went and rebooted 
into Linux again and driver was working on that boot (4th).

After that I removed page_alloc.shuffle=1 and did 2 additional boots, both of them resulted in a non-working driver with 
the error messages about not being able to talk to firmware like I had before on the clean 5.10-rc2:
