Bug ID: 433868
Summary: ACPI resource mode lax causes generates issues with
AMDPU
Product: Powerdevil
Version: 5.21.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general

errors caused by powerdevil running on the setting "acpi_enforce_resources=lax"
SUMMARY
Setting "acpi_enforce_resources=lax" causes powerdevil to conflict with other
devices. In my case it was with AMDGPU and CPU. Resource mode "lax" is used to
be able to access the SMbus controller.
This bug is posted for PowerDevil as uninstalling it resolves the errors.
STEPS TO REPRODUCE
1. Set "acpi_enforce_resources=lax" as kernel parameter
2. Check journal for AMDGPU (dmesg | grep amdgpu)
3.
OBSERVED RESULT
Repetitive error messages in journal for AMDGPU while PowerDevil is installed
and active. No more errors when PowerDevil uninstalled.
EXPECTED RESULT
Setting "acpi_enforce_resources=lax" is not uncommon, so i would expect it to
not cause extra issues. I could however be wrong, if setting it to lax is known
to produce unexpected behaviour, then this bug can be closed. I decided to
report it anyway in case it actually is a bug.
