Freezing and buzzing Product: Power Management Version: 2.5 Hardware: AMD OS: Linux Status: NEW Severity: normal Priority: P3 Component: cpufreq Assignee: linux-pm@vger.kernel.org Reporter: kbii.chris@gmail.com Regression: No Hardware: AMD Ryzen 9 7900x Gigabyte b650 aero g Corsair Dominator Platinum 2x16 6000MHz Kernel tested on: 6.8.2 Arch 6.8.1 Arch 6.6.9 Debian Issue: There has been a static noise coming from my cpu as well as frequent freeze= s. This is nearly constant and makes the computer impossible to use for long d= ue to the sound. Remedy: I have found the issue to disappear completely while using the passive driv= er provided by amd_pstate. The scaling driver must be set to schedutil. This completely mitigates the issue. kernel flags: amd_pstate=3Dpassive cpufreq.default_governor=3Dschedutil Suspicions: I suspect the power management implementation used by amd_pstate_epp to be causing this issue. There is a async param found inside /sys/devices/system/cpu/power that is always set to false whenever amd_pstate_epp is used. My intuition tells me this must be what holds up the system at times while changing c_states or something. Extra: I have seen alot of talk surrounding the fTPM and issues around it but I ca= nnot related these two observations together, hence why I am opening a new issue= . If this is not the right way to go about it mybad, this is my first bug report. --=20 You may reply to this email to add a comment.
