Title: MSI ez CPU debug led is constantly ON when resume from suspend to ram (S3) state Status in linux package in Ubuntu: Confirmed Bug description: When the PC (running latest distribution or mainline PPA Linux kernel - 5.18.6-051806-generic) wakes up from suspend to ram (S3) state, the motherboard CPU ez debug led light stay solid and does not turning off indicating CPU problem. Otherwise (at first glance) the system works as expected, also there is no ACPI error messages in dmesg. The problem seems to be Linux specific since the issue does not appears on Windows 11. The problem is reported on Reddit MSI channel for several Linux distributions: https://www.reddit.com/r/MSI_Gaming/comments/t58dp6/pro_z690a_wifi_ez_debug_cpu_led_turns_red_when/ As additional info one of the processor msr -> MSR_IA32_PERF_CTL (0x199) is restored as 0x1e00 prev value: 0x800 but probably it is not related.
