https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D247306 Bug ID: 247306 Summary: [acpi_ibm] [patch] add cpu fan full-speed level Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: ali.abdallah@suse.com Created attachment 215613 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D215613&action= =3Dedit Add support for running fan in full-speed mode My x220 sometimes runs hot on FreeBSD (when pushing it to its limit). And I start receiving coretemp messages: > coretemp0: critical temperature detected, suggest system shutdown Unfortunately auto mode never sets the fan to spin fast enough to cool down= the cpu, neither level 7 (max currently supported by the driver). The driver do= es not support full-speed (disengaged mode). Attached is a patch to implement that, with documentation updates. Tested on x220, x230, T430 and T61. (Since I submitted many patches in the past to improve acpi support for Thinkpads, I added my name, but feel free to strip it off). --=20 You are receiving this mail because: You are the assignee for the bug.=
