Disassembled DSDT from Dell XPS 13 9360
On the older Dell XPS 13 9360, the warning is also present.

[Bug 218557] New: Kernel regression in acpi/ec.c causing some AMD platforms to limit CPU frequency to < 544Mhz
https://bugzilla.kernel.org/show_bug.cgi?id=218557 Bug ID: 218557 Summary: Kernel regression in acpi/ec.c causing some AMD platforms to limit CPU frequency to < 544Mhz Product: ACPI Version: 2.5 Hardware: AMD OS: Linux Status: NEW Severity: blocking Priority: P3 Component: EC Assignee: acpi...@kernel-bugs.osdl.org Reporter: mpearson-len...@squebb.ca Regression: No Created attachment 305960 --> https://bugzilla.kernel.org/attachment.cgi?id=305960&action=edit Log of system after suspend/resume with frequencies locked There have been various reports of issues on Lenovo P15v G3 AMD and P16v G1 AMD platforms where CPU frequency after suspend/resume is limited to 544MHz I was able to reproduce this reliably on my P16V G1 AMD with the following steps: - Be plugged in - Suspend (s0ix) - Unplug - Resume If then checking the CPU frequencies they are limited to 400 to 544Mhz and cause reduced system performance. The only recovery is to power cycle. I was able to bisect the issue and tracked it down to this commit: https://github.com/torvalds/linux/commit/b5539eb5ee70257520e40bb636a295217c329a50 I've done a 6.8-rc6 build with and without this change and confirmed it is broken/fixed (kernel logs attached). Please let me know how to proceed from here. Thanks Mark -- You may reply to this email to add a comment.
