https://bugzilla.kernel.org/show_bug.cgi?id=65761 Bug ID: 65761 Summary: HD 7970M Hybrid - hangs and errors and rmmod causes crash Product: Drivers Version: 2.5 Kernel Version: 3.13-rc1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: haagch.christoph@xxxxxxxxxxxxxx Regression: No Created attachment 115961 --> https://bugzilla.kernel.org/attachment.cgi?id=115961&action=edit dmesg with multiple issues 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] muxless, so there's no display outputs on the radeon gpu. With 3.13 and dpm and runtime power management enabled by default this should be getting usable. I did not start X this time. (when starting X on the intel gpu quickly after booting (presumably before radeon is initialized) the display output hangs, which is yet another problem). Dmesg seems to contain several issues. 1. While booting it already produces these before even "dpm initialized" is logged: [ 20.120137] WARNING: CPU: 0 PID: 53 at drivers/gpu/drm/drm_mm.c:578 drm_mm_takedown+0x2e/0x30 [drm]() [ 20.120138] Memory manager not clean during takedown. 2. These are just periodically displayed in the tty: [ 79.179928] [drm:r600_ib_test] *ERROR* radeon: fence wait failed (-35). [ 79.181378] [drm:radeon_ib_ring_tests] *ERROR* radeon: failed testing IB on GFX ring (-35). [ 79.182790] [drm:radeon_resume_kms] *ERROR* ib ring test failed (-35). 3. After some time in a tty, I did "rmmod radeon" and got some other issues ending with [ 192.663059] Fixing recursive fault but reboot is needed! and then, after a little while a lot of other errors happen, but they are not captured here in the dmesg. -- 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
