Package: fancontrol Control: reopen -1 Control: found 1:3.6.0-8 Version: 1:3.6.0-8 Followup-For: Bug #664141
I've just experienced this behaviour on this (sid) machine, only installed this week, where fancontrol controls the fan of an ASRock RX 6x00 GPU card. The fan came on full speed after leaving suspend and stayed there. The log indicates that fancontrol had been restarted, exited with error: Aug 30 09:48:47 isildor2 kernel: PM: suspend entry (deep) (...) Aug 30 09:48:56 isildor2 kernel: amdgpu 0000:2d:00.0: amdgpu: Failed to set manual fan control mode (...) Aug 30 09:48:56 isildor2 kernel: amdgpu: manual fan speed control should be enabled first Aug 30 09:48:56 isildor2 kernel: amdgpu: manual fan speed control should be enabled first Aug 30 09:48:56 isildor2 systemd-sleep[223073]: System returned from sleep state.

Aug 30 09:48:56 isildor2 systemd[1]: systemd-suspend.service: Deactivated successfully. It seems that the original fix of this bug is still prone to a race condition: the restart attempts seems to happen before the IO gets ready to accept manual fan mode. My fix was to add a drop in to the fancontrol.service: [Service] Restart=on-failure (This might even make /lib/systemd/system-sleep/fancontrol obsolete; bonus is that if fancontrol crashes, it will also auto-restart, possibly saving some hardware from overheating…) -- Cheers, tobi -- System Information: Debian Release: trixie/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'stable-security'), (500, 'oldstable-security'), (500, 'oldoldstable'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (500, 'oldstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.4.0-3-amd64 (SMP w/12 CPU threads; PREEMPT) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages fancontrol depends on: ii init-system-helpers 1.65.2 fancontrol recommends no packages. fancontrol suggests no packages. -- no debconf information
