dmesg of kernel w/ gpu reset info

Without 600_DEBUG=sb game loads but poor performance

With 600_DEBUG=sb GPU resets over and over unless VT switch out of X to console.

cmdline: BOOT_IMAGE=/vmlinuz-3.11.0-0.rc7.git2.2.fc21.x86_64 root=/dev/mapper/fedora-root ro rd.lvm.lv=fedora/swap rd.md=0 rd.dm=0 rd.luks=0 vconsole.keymap=us rd.lvm.lv=fedora/root rhgb quiet slub_debug=- cgroup_disable=memory radeon.dpm=1 console=tty0 console=ttyS0,38400n8 LANG=en_US.UTF-8    

See dmesg attachment for gpu reset information

GPU Resets might be related to:  https://bugs.freedesktop.org/show_bug.cgi?id=59649

GLSL mis-compilation however is separate issue
Comment 5 Shawn Starr 2013-09-11 04:57:46 UTC
Multiple issues... GPU reset issue was fixed, this is GLSL error, reopening with new bug, not SB related
