That should be the dmesg output from unpached kernel This should be the patched output. |

system randomly freeze This is a driver bug, not a sysfs one, sysfs is warning that the driver is doing something wrong. That's not even a driver bug, it's an ACPI APEI problem. It appears that your system has duplicated HEST error source ID, which may be a firmware bug. But we need to fix APEI driver to provide better error information. I will do that. But that should not cause your system randomly freezing. Please try to use "hest_disable=1" in your kernel command line to test. Created attachment 62402 [details]
Detect duplicated hardware error source ID in HEST
njin, Can you help us to test the patch attached?
Hi. I am the owner of that Thinkpad device. Maybe I could help, but can you tell me how? Thanks. Mathias, can you test the patch in comment #5? I will do that as soon as possible. I need a little time to find out how to compile a kernel. I did not do that until now. So please be patient. Thanks. Created attachment 63142 [details]
