https://bugzilla.kernel.org/show_bug.cgi?id=212107 Bug ID: 212107 Summary: Temperature increase by 15°C on radeon gpu Product: Drivers Version: 2.5 Kernel Version: 5.11 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: martin.tk@xxxxxxx Regression: No Created attachment 295701 --> https://bugzilla.kernel.org/attachment.cgi?id=295701&action=edit dmesg.log Since upgrading my kernel from 5.10.16 to 5.11.3 I noticed an increase in temperature on my AMD gpu (Radeon RX550). I later tried both 5.10.20 and 5.11.4 and I can notice the increase in temperature only on 5.11 kernel. In addition to the temperature I noticed that the fan on gpu would spin up to max rpm for a second or two right after waking up the PC from sleep. I've never noticed such behaviour before. I can't see any errors in the logs and the system seems to be running normal. No crashes nor degraded performance either. I check temperature using sensors utility. For 5.11.4 it shows the following: 1st run: amdgpu-pci-0100 Adapter: PCI adapter vddgfx: 962.00 mV fan1: 963 RPM (min = 0 RPM, max = 3500 RPM) edge: +54.0°C (crit = +97.0°C, hyst = -273.1°C) power1: 9.13 W (cap = 36.00 W) 2nd run few minutes later: amdgpu-pci-0100 Adapter: PCI adapter vddgfx: 825.00 mV fan1: 978 RPM (min = 0 RPM, max = 3500 RPM) edge: +47.0°C (crit = +97.0°C, hyst = -273.1°C) power1: 7.19 W (cap = 36.00 W) 5.11.3: amdgpu-pci-0100 Adapter: PCI adapter vddgfx: 962.00 mV fan1: 991 RPM (min = 0 RPM, max = 3500 RPM) edge: +57.0°C (crit = +97.0°C, hyst = -273.1°C) power1: 9.08 W (cap = 36.00 W) these two are on 5.10.16: amdgpu-pci-0100 Adapter: PCI adapter vddgfx: 787.00 mV fan1: 976 RPM (min = 0 RPM, max = 3500 RPM) edge: +39.0°C (crit = +97.0°C, hyst = -273.1°C) power1: 6.11 W (cap = 36.00 W) amdgpu-pci-0100 Adapter: PCI adapter vddgfx: 962.00 mV fan1: 976 RPM (min = 0 RPM, max = 3500 RPM) edge: +40.0°C (crit = +97.0°C, hyst = -273.1°C) power1: 8.26 W (cap = 36.00 W) I'm attaching parts of dmesg log I thought relevant. -- You may reply to this email to add a comment.
