Can you please bisect the WMI core commits from this cycle? This should do the trick: $ git bisect start v6.15 v6.14 -- drivers/platform/x86/wmi.c You are using Arch so you can use $ make localmodconfig $ make -j$(nproc) pacman-pkg to compile. Maybe (Cc+) Armin Wolf can give us some insight too. > > Compare to 6.14.10: > > dell_wmi: Received WMI event (02 00 10 00 50 01 00 00 00 00 00 00 00 00 0= 0 00 > 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0= 0 00 > 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00) > dell_wmi: Process buffer (02 00 10 00 50 01) > dell_wmi: Key with type 0x0010 and code 0x0150 pressed @Armin JFYI: I have this exact event in my system (Alienware x15 r1) but I can't reproduce the bug. The WMI event is received just fine. I also tried upstream v6.15 and v6.16 and this event still works fine. > > Also I noted difference in loaded modules. `lsmod | grep dell` In 6.15: > > dell_pc 12288 0 > platform_profile 16384 1 dell_pc > dell_rbtn 20480 0 > dell_laptop 45056 0 > dell_smm_hwmon 28672 0 > dell_wmi 28672 1 dell_laptop > dell_smbios 36864 3 dell_wmi,dell_pc,dell_laptop > dell_wmi_sysman 61440 0 > firmware_attributes_class 12288 1 dell_wmi_sysman > dcdbas 20480 1 dell_smbios > dell_wmi_descriptor 20480 2 dell_wmi,dell_smbios > dell_lis3lv02d 16384 0 > dell_smo8800 16384 0 > rfkill 45056 9 > iwlmvm,bluetooth,dell_laptop,dell_rbtn,cfg80211 > sparse_keymap 12288 2 intel_hid,dell_wmi > video 81920 3 dell_wmi,dell_laptop,i915 > wmi 32768 7 > > dell_wmi_sysman,video,dell_wmi,wmi_bmof,dell_smm_hwmon,dell_smbios,dell_w= mi_descriptor > > Compare to 6.14.10: > > dell_pc 12288 0 > platform_profile 16384 1 dell_pc > dell_rbtn 20480 0 > dell_laptop 45056 0 > dell_smm_hwmon 28672 0 > dell_wmi 28672 1 dell_laptop > dell_smbios 36864 3 dell_wmi,dell_pc,dell_laptop > dcdbas 20480 1 dell_smbios > dell_wmi_sysman 61440 0 > dell_lis3lv02d 16384 0 > firmware_attributes_class 12288 1 dell_wmi_sysman > dell_wmi_descriptor 20480 2 dell_wmi,dell_smbios > rfkill 40960 9 > iwlmvm,bluetooth,dell_laptop,dell_rbtn,cfg80211 > dell_smo8800 16384 0 > sparse_keymap 12288 2 intel_hid,dell_wmi > video 81920 3 dell_wmi,dell_laptop,i915 > i8042 57344 1 dell_laptop > wmi 32768 7 > > dell_wmi_sysman,video,dell_wmi,wmi_bmof,dell_smm_hwmon,dell_smbios,dell_w= mi_descriptor > > Note in "good" case i8042 is loaded and used by dell_laptop module, in "b= ad" > case it isn't. > I modprobed i8042 in 6.15 just in case. Expectedly, it had no effect. Yes, as you already mentioned the i8042 module is unrelated to this bug. --=20 You may reply to this email to add a comment.
