[Test Case] This can be triggered by checkbox warm reset stress test: $ checkbox-cli run com.canonical.certification::stress/reboot [Where problems could occur] This imports fixes requiring both kernel driver and proprietary firmware updates, the firmware part might cause instability or so.

Boot into Ubuntu desktop 2. Check if MT7921 obtains IP, ping gateway and ping 8.8.8.8 3. No response, need to do cold boot to recover 4. The issue is easily be seen after warm reset stress, I locally test warm reset stress for 100 times [Results] Expected: Has traffic and response by ping Actual: No response To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1958286/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
