Pavel, can you test with that patch on v5.10-rc2 and provide the ath11k
log messages? Preferably both before and after reverting commit
7fef431be9c9. Do note that I'm not expecting the debug patch to fix
anything, in your case it's just for providing more debug info.

With vt-d disabled on v5.10-rc2 before the revert I see:
