In addition, cold booting on battery power, then plugging the charger generates the "asus_wmi: Unknown key cf pressed" message. I remember seeing a different "key" one time I was quickly plugging and unplugging the charger, but not which specific key. Created attachment 1627143 [details]
Dmesg with rawhide kernel
I managed to install the Rawhide kernel, and got some more output from the bug. Please find a new dmesg attached.
Is there anyone looking at this? I am experiencing the exact same issue on my ASUS UX391UA laptop. This seems to be related to bug 1745924. As I mentioned there I have been talking to the upstream ucsi driver maintainer (Heikki Krogerus) and he would like for someone who is having this problem to file a bug at bugzilla.kernel.org and work through the issue with him there. Please go to https://bugzilla.kernel.org/enter_bug.cgi?product=Drivers choosing USB as component. So that he can work directly with you to debug this. Please post a link to the new bug here, then I can assign the kernel.org bug to him. Thanks Hans. I have submitted the bug: https://bugzilla.kernel.org/show_bug.cgi?id=206365 Thank you, I've assigned the bug to Heikki and also send him an email about it. Lets continue this in the bugzilla.kernel.org bugzilla. Ping? Many people seem to be hitting this, also see bug 1762031, bug 1785972, bug 1798810 and bug 1800913. Can someone seeing this issue please provide the information requested in the upstream bug to help debug this ? : https://bugzilla.kernel.org/show_bug.cgi?id=206365#c5 After checking the upstream bug one more time, I noticed that yesterday Heikki provided a patch to test. I've started a test/scratch build of a Fedora kernel with that patch added: https://koji.fedoraproject.org/koji/taskinfo?taskID=41491485 (note still building atm, this takes a couple of hours) See here for generic instructions for installing a kernel directly from koji: https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt If you can reproduce the bug, by e.g. unplugging your chager, then please give this new kernel a try and let us know if it fixes things. If this new kernel does not fix things, please collect the debugging info described here: https://bugzilla.kernel.org/show_bug.cgi?id=206365#c5 The kernel test build is ready for downloading, please give it a try. Upstream has provided a second patch which should fix this. I've done a scratch-build of a Fedora kernel with that patch added: https://koji.fedoraproject.org/koji/taskinfo?taskID=41491485 Note the build has already finished, so you can get it right away. See here for generic instructions for installing a kernel directly from koji: https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt If you can reproduce the bug, by e.g. unplugging your chager, then please give this new kernel a try and let us know if it fixes things. If this new kernel does not fix things, please collect the debugging info described here: https://bugzilla.kernel.org/show_bug.cgi?id=206365#c5 I accidentally posted the link to the old, first test build in my last comment. The correct link for the new build is: https://koji.fedoraproject.org/koji/taskinfo?taskID=41750652 2 patches which should fix these have been posted upstream. These 2 patches are headed on their way to the mainline kernel. I've added them as downstream patches to the Fedora kernels for F30 and F31 for now. These 2 patches will be in the next official Fedora kernel build for f30 + f31, which will be either 5.5.9-201.fc31 or 5.5.10. There are multiple bugs open for this issue, since these 2 patches should fix all cases, I'm marking all the bugs as duplicates of bug 1785972, where most of the discussion on this has happened. Please give the next official kernel builds a try once it hit updates-testing, and add a note to bug 1785972 if it resolves things for you (or not). *** This bug has been marked as a duplicate of bug 1785972 *** |
