On what firmware version? I run it on a Qualcomm RB3 board with Qualcomm SDM845 and WCN3990. However on that kernel I did not manage to WiFi actually work - regardless of that patch - so I would no count it yet as fully tested. It would be great if someone would provide some tests. I saw Steev's replies - thanks! Best regards, Krzysztof
