Hi, sorry for barging in but I'm also hitting this on the same graphics card (NVS 4200M) on a Dell Latitude E6520 running Arch Linux. I'm trying to use PRIME for a VA-API + VDPAU setup and also for some games but as soon as I start I get this message in dmesg : kernel: nouveau E[ PFIFO][0000:01:00.0] INTR 0x00800000 kernel: nouveau W[ PFIFO][0000:01:00.0] INTR 0x01000000: 0x00000005 I'm running the 3.15.6-1-ARCH kernel with the following packages: intel-dri-git 10.3.0_devel.64000-1 lib32-intel-dri-git 10.3.0_devel.64007-1 lib32-mesa-git 10.3.0_devel.64007-1 lib32-mesa-libgl-git 10.3.0_devel.64007-1 lib32-nouveau-dri-git 10.3.0_devel.64007-1 lib32-opencl-mesa-git 10.3.0_devel.64007-1 lib32-svga-dri-git 10.3.0_devel.64007-1 libdrm-git 2.4.54.19.gc0b34dc-1 mesa-git 10.3.0_devel.64000-1 mesa-libgl-git 10.3.0_devel.64000-1 nouveau-dri-git 10.3.0_devel.64000-1 opencl-mesa-git 10.3.0_devel.64000-1 xf86-video-nouveau-git 1.0.10.34.gedd1608-1 If I stop the application the uses the NVIDIA card as soon as I see the message, everything is OK. But if I continue, X freezes and the only way I can regain control is by a cold reboot.
