Bug ID: 99316 Summary: Radeon crash when laptop on AC power Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: major Priority: medium Component: DRM/Radeon Assignee: dri-devel at lists.freedesktop.org Reporter: LordSamanon at gmail.com Created attachment 128807 --> https://bugs.freedesktop.org/attachment.cgi?id=128807&action=edit AC Power Unigine Heaven dmesg I have a Dell laptop with an Intel iGPU and a Radeon dGPU (a Firepro W5130M, recognized as a Radeon HD 8830M by lspci). Whenever I attempt to use the Radeon card via DRI_PRIME=1 while the laptop is plugged in, the card crashes. When on battery the card performs fine. One way I have tested this is with glxgears. Often glxgears will work the first time it is run, but if it is closed and then opened a few seconds later, it will crash. I have also tried running programs like Portal 2 and Unigine Heaven. These always hang. Unfortunately the error messages produced in dmesg are not the most consistent. Sometimes I get a backtrace, sometimes even a kernel panic on reboot. I'll post the various logs I have. One thing I have found is that glxgears does not crash if I use radeon.runpm=0, however it still hangs when running something like Portal. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
