https://bugzilla.kernel.org/show_bug.cgi?id=187581 Bug ID: 187581 Summary: Nouveau GPU Lock Up with 2D Acceleration Product: Drivers Version: 2.5 Kernel Version: 4.8.6 Hardware: PPC-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: jeffbai@xxxxxxxx Regression: No Happened to get 2 FX4500's for my PowerMac G5 11,2, but it didn't seem willing to cooperate. Without nouveau.noaccel=1 in the kernel parameter, the system starts fine, but X would only work with fbdev driver - as GPU locks up at early stages of startup (dmesg attached above). With nouveau.noaccel=1 in the kernel parameter, system starts fine without the lock up message, but X will **still** only work with fbdev - using nouveau with result in a looped output of the following message: "nouveau 0000:0a:00.0: DRM: 0x13DC: Parsing digital output script table" And the system is inaccessible, this also appears to hang any `systemctl stop lightdm` operation and even the `reboot` command itself. --------------------------- Xorg-Server version: 1.18.4 Kernel version: 4.8.6 xf86-video-nouveau version: 1.0.12 --------------------------- A similar bug report is filed here due to uncertainty on the origin of the issue. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
