(It started after a kernel update; don't know which one -- years ago) While at the time, I ran Windows on the same laptop every now and then, it would work correctly. My card reports `lspci | grep VGA`: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XT [Radeon HD 8870M / R9 M270X/M370X] Without radeon.dpm or with radeon.dpm=1, the card runs hot: within minutes fans will run at 3300+ RPM keeping the card barely below 66 degC. Note that `radeontop` reports an `Graphics pipe` of 0.00% most of the time. After discovery of the setting radeon.dpm yesterday, after a few failed trials to set the setting to '1', I set `radeon.dpm=0`. After letting the PC cool down (turned off) and starting again, the PC ran 10 minutes without fans and is running at 53 degC with fans running at 2100 RPM. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
