https://bugzilla.kernel.org/show_bug.cgi?id=79071 Bug ID: 79071 Summary: Hang with dpm radeon hd 5750, pcie 1.1 motherboard Product: Drivers Version: 2.5 Kernel Version: 3.16-rc2 (all dpm kernels) Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: jonathan@xxxxxxxxxxxxx Regression: No Created attachment 141161 --> https://bugzilla.kernel.org/attachment.cgi?id=141161&action=edit dmesg New bug report but problem been around since start of dpm code. Only now tried out few more tests. I think (without certainty) underlying cause is the old motherboard. (Have no other system to swap to.) System runs stable until running games. Found cogs a good test case as it usually hangs quickly on the menu. /sys/class/drm/card0/device/power_dpm_force_performance_level No problems when low. Set to high (ie not dynamic) still hangs in games. Tried (modified for cypress_dpm.c) https://bugs.freedesktop.org/attachment.cgi?id=86424 no fix. Setting eg_pi->vddci_control = false; Working so far. Any refined patch to test much appreciated. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
