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?
