Thank you for filing this bug and providing all the logs. At a first look it looks like the problem is missing powerdown gpio support in the hi556 driver. I'll look into preparing a patch + a Fedora kernel with that patch after the holidays (I'll be back January 6th, but I'll have a lot of things to go through then).

I'm afraid it is going to take a little longer before I will get around to looking into this and providing a test kernel. I'm fully booked this week, so hopefully next week. Also my initial analysis of a missing powerdown pin support in the hi556 driver is wrong. Looking at this again these lines from the kernel log are the problem: Dec 21 12:16:59 fedora kernel: int3472-discrete INT3472:01: unknown \_SB.GPI0 pin 83 active-high Dec 21 12:16:59 fedora kernel: int3472-discrete INT3472:01: GPIO type 0x12 unknown; the sensor may not work Type 0x12 is a handshake pin, but is unclear yet how to handle this pin. So fixing this is going to be tricky / will likely take a while I'm afraid. Note to self: This is an Alder Lake machine. Sorry for being slow in getting back to you. I just finished a patch series to deal with the special handshake signal your laptop seems to need and posted version 1 of this upstream: https://lore.kernel.org/platform-driver-x86/20250325161340.342192-1-hdegoede@redhat.com/ I've build a test-kernel with these patches, please give this a go: https://koji.fedoraproject.org/koji/taskinfo?taskID=130775742 Here are some instructions for directly installing a kernel from koji: https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt In the mean time handshake GPIO support has been added to the Fedora kernels and I've just done another Fedora test-kernel build with some extra hi556 fixes for bug 2368506): https://koji.fedoraproject.org/koji/taskinfo?taskID=133212953 This kernel is ready to download and install now. For instructions for directly installing a kernel from koji (Fedora's buildsystem) see: https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt Please give this kernel a try and if things still do not work please collect new kernel logs using "journalctl -b 0 -k > kernel.txt". |
