Bug ID: 217720 Summary: System powers down when running particular programs Product: ACPI Version: 2.5 Hardware: AMD OS: Linux Status: NEW Severity: high Priority: P3 Component: Power-Processor Assignee: acpi_power-proces...@kernel-bugs.osdl.org Reporter: yifan...@rochester.edu Regression: No I have a server with AMD EPYC 7773X 64-Core Processor (ucode: 20230625.ee91452d-5) running on supermicro h12ssl-i. I mistakenly enabled the ACPI-based driver instead of amd-pstate. It turns out that, when running a particular program (the source code is at https://github.com/SchrodingerZhu/paguroidea/tree/acpi-cpupower-bug and I invoked `cargo bench`), the whole system powers down immediately (the video output is cut; the power LED is down; the BMC seems to be alive as the fan is still running but I cannot get any log from SEL). I reproduced this under both schedutil and performance governor (others are not tested). I switched to amd_pstate=guided now, and the problem is gone. So I think this should be a problem with the ACPI driver. -- You may reply to this email to add a comment.
