Hi! I’m running a Beelink SEi12 (model ALDER109, BIOS date 2022-12-01) on Linux Lite (Ubuntu 22.04 base), and I’ve been dealing with near-daily system crashes where the fans ramp to maximum and the machine becomes completely unresponsive and requires a hard reset.
Looking at the kernel logs, I’ve found the same ACPI errors repeating every boot:
ACPI Error: Aborting method \_SB.PC00.LTHx._CRS due to previous error (AE_AML_INVALID_RESOURCE_TYPE)
ACPI Error: Method execution failed \_SB.PC00.LTHx._CRS due to previous error (AE_AML_INVALID_RESOURCE_TYPE)
(x ranges from 1 to 5)
These LTH devices I believe correspond to the Thunderbolt/USB4 controller. From what I understand, the firmware’s ACPI tables for these ports are returning invalid data to the OS.
These errors appear in the kernel log every boot, and may be related to the crashes
Kernel parameters pcie_aspm=off do not stop the crashes.
What I think could help:
A BIOS/firmware update that corrects the _CRS method for these Thunderbolt/USB4 devices so it returns valid data.
Or a BIOS setting to fully disable the Thunderbolt/USB4 controller at the firmware level, removing the LTH entries entirely. I am also open to any other recommendations if this is a known issue that’s been addressed before.
System details:
Model: SEi12 / ALDER109
BIOS date: 2022-12-01
OS: Linux Lite (Ubuntu 22.04 base)
Kernels tested: 5.15.0-151, 6.8.0-65
Problematic ACPI devices: _SB.PC00.LTH1 .. _SB.PC00.LTH5
Thanks in advance for any help
Here’s my BIOS screenshot if helpful
