https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253288 Bug ID: 253288 Summary: hwpstate_intel: Wedges under any kind of load on ThinkPad Carbon X1 Gen 8 Product: Base System Version: 13.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: ltning-freebsd@anduin.net Only workaround is to add hint.hwpstate_intel.0.disabled=1 to /boot/loader.conf, but this makes power consumption go through the roof and generates a lot of dmesg warnings about overheating, suggesting the computer be switched off. BIOS powersaving settings have no bearing on this problem. The problem has existed since early 2020, and got significantly worse in the Jan/Feb timeframe. However sporadic hangs with kernels from late 2019 have also been observed. Kernel/world version stable/13 106efdb060ae523a88caf5ddc3516500cf5b1d64 -- You are receiving this mail because: You are the assignee for the bug.help
