Oh, very interesting. Thanks a lot for the bisection, otherwise we would have never found out whats causing this. David & mm folks: Pavel noticed that his QCA6390 Wi-Fi 6 device (driver ath11k) failed on v5.10-rc1. After bisecting he found that the commit below causes the regression. I have not been able to reproduce this and for me QCA6390 works fine. I don't know if this needs a specific kernel configuration or what's the difference between our setups. Any ideas what might cause this and how to fix it?
