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
        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 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.
