** Description changed: - This bug is for tracking purpose. + I tested the upstream stable kernel 4.19.191, also could reproduce + this issue, and reported this testing result to stable mail list. + + + [Impact] + On the Dell300x machine, after system suspend and resume, the wifi + and bluetooth can't work anymore. + + [Fix] + Revert a patch which was applied to bionic kernel from stable update. + + [Test] + Booting up with the patched kernel, run $sudo rtcwake -m freeze -s 10, + then check dmesg to make sure there is crashing log, and run 'nmcli d + wifi' and 'bluetoothctl, power on, scan on', all worked well. + + [Where problems could occur] + After applying this SRU, the rsi wifi and bluetooth could have come + change, like wifi and bluetooth can't work well after resume, but this + possibility is very low, I already run '$sudo rtcwake -m freeze -s 10' + for 50 times, the wifi and bluetooth still worked well.
