dmesg output

On my muxed hybrid system (Lenovo IdeaPad U455) X works fine with IGD gpu
(RS780M), but screen gets garbled when DIS gpu (RV710) is active. In dmesg
output there are lots of following messages:
[drm:r600_packet3_check] *ERROR* bad START_3D
[drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

My system is:
Lenovo IdeaPad U455 with RS780M and RV710 gpus.
linux-3.7.0-rc3+
libdrm-2.4.39
xf86-video-ati-6.14.6
mesa-9.0
glu-9.0
xorg-server-1.12.3
