No audible fan ramp; RPMs remain 0. =E2=80=A2 dmesg shows: =E2=80=9Chp_wmi: query 0x4c returned error 0x6=E2= =80=9D. =E2=80=A2 /sys/class/thermal/cooling_device[0-4]: type=3DFan, max_state= =3D1, cur_state stays at 0. Expected behavior: =E2=80=A2 On HP Omen models with working hp-wmi, =E2=80=9CBoost=E2=80=9D = (pwm1_enable=3D0) briefly ramps fans and RPM becomes non-zero; rpm values are readable via sensors hp-isa-0000. (ArchWiki documents this expected behavior for Omen 16 models.= )=20 Reproducer: 1) Boot into 6.16.10 (Arch kernel). 2) sensors: fan1/fan2 show 0 RPM. 3) echo 0 > /sys/devices/platform/hp-wmi/hwmon/hwmon*/pwm1_enable =E2=86=92 value reverts to 2; no fan ramp; dmesg logs =E2=80=9Chp_wmi:= query 0x4c error 0x6=E2=80=9D. 4) cooling_device[0..4] report Fan (max_state=3D1) but cur_state stays 0. What I tried: =E2=80=A2 Verified AC adapter online. =E2=80=A2 Tried platform_profile=3Dperformance and power-profiles-daemon. =E2=80=A2 Collected ACPI tables (acpidump -b) and full logs. Hypothesis: =E2=80=A2 This board-id (8BAB) might not be covered by current hp-wmi DMI= allow-lists or uses different HPWMI method IDs on newer firmwares; the firmware rejects 0x4c here. Guidance on traces/patch to test alternate query paths would be appreciated. Attachments: =E2=80=A2 Tarball with: dmesg, journalctl -b, lsmod, modinfo hp_wmi, sens= ors, hp-wmi hwmon listings, cooling devices/thermal zones, dmidecode (serial/UUID redacted), ACPI tables (acpidump -b). I=E2=80=99m happy to run debug builds, provide disassembled DSDT/SSDT snipp= ets around WMI devices, and test patches. Thanks! --=20 You may reply to this email to add a comment.
