Created attachment 67947 [details] dmesg When booting kernel with nouveau.noaccel=0 and running any application uses 3d acceleration(for example weston or gears on X or kwin effects) GPU is hang. Problems only with gt520, or on all 5xx series(fermi)? How can I help to fix that? Installed packages: $ uname -a Linux localhost 3.5.4-1-ARCH #1 SMP PREEMPT Sat Sep 15 08:12:04 CEST 2012 x86_64 GNU/Linux mesa-git libdrm-git
Fixed in 3.8+ kernel
