All seven modules blacklisted: blacklist ideapad_laptop blacklist lenovo_wmi_other blacklist lenovo_wmi_helpers blacklist lenovo_wmi_capdata01 blacklist lenovo_wmi_hotkey_utilities blacklist sparse_keymap blacklist platform_profile `update-initramfs -u` after =E2=80=94 without the initramfs rebuild ideapad_laptop still loads early. Post-reboot, `lsmod` confirms none of the seven is loaded. Testing only against /dev/input/event2 (AT Translated Set 2 keyboard), since event5/event6 paths are gone with these modules blacklisted. Working state (post-boot, pre-suspend): volume-up Fx press -> MSC_SCAN 0xb0 KEY_VOLUMEUP volume-down Fx press -> MSC_SCAN 0xae KEY_VOLUMEDOWN mute Fx press -> MSC_SCAN 0xa0 KEY_MUTE So event2 works normally without any of these modules =E2=80=94 the EC is translating Fx to the E0-extended media scancodes and atkbd is delivering them as expected. Broken state (after s2idle resume, ~21 min suspend): volume-up Fx press -> MSC_SCAN 0x3d KEY_F3 volume-down Fx press -> MSC_SCAN 0x3c KEY_F2 mute Fx press -> MSC_SCAN 0x3b KEY_F1 Same machine, same kernel, same blacklist still in effect. The EC has stopped translating Fx to media scancodes and is emitting raw F-key scancodes (0x3b..0x3d =3D F1..F3). Conclusion: the regression reproduces with ideapad_laptop, lenovo_wmi_*, sparse_keymap, and platform_profile all absent. None of them is in the code path that breaks. Matches your firmware/EC hypothesis. Attaching the two evtest captures (event2, --grab): evtest-blacklisted-working.txt evtest-blacklisted-broken.txt Happy to run further tests =E2=80=94 e.g. dynamic_debug on the acpi/ec path across suspend/resume, `pm_test core/platform/processor` to narrow the phase, or acpidump/ectool snapshots in both states. Let me know what would help most. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
