https://bugzilla.kernel.org/show_bug.cgi?id=81281 Bug ID: 81281 Summary: 8970M boot problems since 3.13 with dpm Product: Drivers Version: 2.5 Kernel Version: 3.16.0-rc5 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: sharkgoesmad@xxxxxxxxx Regression: No Created attachment 144531 --> https://bugzilla.kernel.org/attachment.cgi?id=144531&action=edit syslog I am using MSI GX60 3BE 240US, which is a AMD/AMD hybrid, sporting a10-5750m Richland apu and super-powerful HD 8970M. Since kernel 3.13, my laptop is unable to boot unless ran with radeon.dpm=0. Worth to note that 3.12 with radeon.dpm=1 works mighty fine. While trying different kernel versions and inspecting syslog, it seems that in all cases the problem starts with the following line: [drm:r600_ring_test] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD) In 3.13-3.15 it results in system restart when the login screen shows up. In 3.16 however, the screen freezes and no restart occurs. The system responds normally when pressing power button and shuts down. Attached is the piece of the syslog and Xorg.0.log when ran with 3.16-rc5. Any help would be greatly appreciated. Thanks. -- 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
