I've got the exact same problem on Thinkpad P16s Gen1 (AMD) Same problem here Model: T14 Gen 3 AMD Type: 21CF UEFI BIOS: 1.35 (newest) ECP: 1.25 (newest) I've tested: Debian Stable - Kernel 6.1.38 Debian Testing - Kernel 6.3.7 Debian Unstable - Kernel 6.4.4 Same problem when Thinkfan 1.3.1 is enabled and also when running pwmconfig from fancontrol package. Unfortunately using journalctl gives nothing. Whole laptop freezes before journalctl writes anything. Some additional information Same hardware as @Piotr, kernel 6.5.1 (NixOS) I've managed to troubleshoot a bit further when writing my own fan control script in python. If we write fan speeds too fast the kernel locks up super-hard instantly. If you're playing sound while it hangs it'll keep looping the same second or so of sound, not sure for how long because it's unbearable. Writing fan speeds once per second is enough to freeze the kernel. https://github.com/Lillecarl/nixos/blob/master/fancontrol.py This is the script I used to perform the tests. |
