Bug ID: 206489
Summary: XPS 13 ICL Ice Lake: kworker kacpi_notify spinning
wheels
Product: ACPI
Version: 2.5
Kernel Version: 5.5.0
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: EC
Assignee: acpi...@kernel-bugs.osdl.org
Reporter: l...@kraav.com
Regression: No
Created attachment 287291
--> https://bugzilla.kernel.org/attachment.cgi?id=287291&action=edit
acpidata.dat
Something is continously triggering gpe6D, making kworker/0:0+pm and
kworker/0:2-kacpi_notify work overtime.
