Xorg.0.log

Hi all!

I've installed the next packages from the Oibaf PPA in a workstation with
Ubuntu 16.04, kernel 4.4.0-62-generic and BONAIRE amd card.

* libdrm 2.4.75+git1702030630.fe7cb3~gd~x_amd64
* libva 1.7.1-2~gd~x_amd64
* llvm 4.0_4.0~+rc1-1~gd~x_amd64
* mesa 17.1~git1702090730.f3d911~gd~x_amd64
* wayland 1.11.0-2~gd~x_amd64
* xserver-xorg-video-amdgpu 1.2.99+git1701262000.49b092~gd~x
* xserver-xorg-video-ati 7.8.99+git1702081933.1351e4~gd~x

I'm using the radeon driver with the next config file:

20-device.conf

Section "Device"
    Identifier "Device0"
    Driver "radeon"
    Option "AccelMethod" "glamor"
    Option "DRI" "3"
    Option "TearFree" "on"
    Option "ColorTiling" "on"
    Option "ColorTiling2D" "on"
EndSection

The Xorg runs ok, the glxgears works ok but when I run my OpenGL app I get a
black screen with some artifacts and the Xorg.0.log begins to show the next
trace:

[   306.739] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Cannot
allocate memory
[   306.756] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Cannot
allocate memory
[   306.772] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Cannot
allocate memory
[   306.789] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Cannot
allocate memory
[   306.806] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Cannot
allocate memory

I've find the message in the 'src/drmmode_display.c' from
'xserver-xorg-video-ati-1:7.8.99' but I don't know whats the origin of the
problem... What can I do?

Thanks!
Jorge
