https://bugs.freedesktop.org/show_bug.cgi?id=95282 Bug ID: 95282 Summary: system hang on video playback via vdpau Product: xorg Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: critical Priority: medium Component: Driver/nouveau Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org Reporter: estellnb-7Km2I/eHSAQdnm+yROfE0A@public.gmane.org QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org Yesterday I have installed the proprietary firmware for nouveau as described under wiki/VideoAcceleration/#firmware and now my machine hangs reliably on start of video playback. If vdpau is not used (i.e. by specifying xine -V XShm xy.mkv) then it does not hang. It first starts to hang, then there is a short moment where it reacts on pressing num lock and where playback continues and then it hangs forever. When switching to vt02 before playback starts you can see several messages; it also reacts on Alt-PrnScr-l/m/p printing out that it would now print the memory/registers/backtraces but then does not actually print them unless you presss Alt-PrnScr-C. There appears to be nothing in the log (switched to vt02 is the last message in the xorg.0.log).
