Created attachment 127956 [details] dmesg without nouveau.noaccel=1 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 --------------------------- I would happily donate one of my FX4500's to one who's willing to investigate this issue.
