my system is working as an htpc and is running fine, no crashes or oops
slim is login my user and starts xbmc automatic 
xbmc in fullscreen is the only graphical application
the system is connected to my tv through hdmi

is spam the whole time with page filp errors
if i leave xbmc alone, so the log is spam every few seconds with page flip
errors

Do you still have the issue with the latest 3.8 kernel from Linus that contains
the patch mentioned in the last comment in bug 58659?

compiled mesa again from master git branch (tree   
7cbc1aafe166dd925c5626c7118f523c8b75ae6d) and got this in dmesg
[    9.917097] glxinfo[2482]: segfault at 0 ip           (null) sp
00007ffffc441708 error 14 in glxinfo[400000+6000]
in the end, xbmc doesn't show up

i went back to mesa-9.0.2 and linux-3.8.0-rc5
also here, the Xorg.0.log is spam the whole time with flip errors

the same is with linux-3.7.4 and mesa-9.0.2
i never had a look at my Xorg.0.log when i was using linux-3.7.x and mesa-9.0.x
hmm ... the log-spam was always there?

so what is causing to spam the Xorg.0.log with these flip errors?

While that is happening, can you write 2 to /sys/module/drm/parameters/debug
and capture some debugging output from dmesg?

* today i recompiled mesa from master git (tree   
d276e9294d1f1218e374d43c1320b376ee265ad4) and linux-3.8.0-rc5
* xbmc is starting and working fine again
* the flip errors still appears in /var/log/Xorg.0.log
* with "echo 2 > /sys/module/drm/parameters/debug" nothing special in dmesg
(watched a 40min-video)
* "echo 1 > /sys/module/drm/parameters/debug" gives a bunch of lines (see
attachment dmesg_debug_1 )

Hmm, so maybe the EBUSY error is coming from this code in
drm_mode_page_flip_ioctl():

        if (crtc->fb == NULL) {
                /* The framebuffer is currently unbound, presumably
                 * due to a hotplug event, that userspace has not
                 * yet discovered.
                 */
                ret = -EBUSY;
                goto out;
        }


What does xrandr --current say when the problem occurs? After that, does
running xrandr without arguments make any difference?

--- Comment #9 from Michael Lange <michaell@gmx.org> ---
an option in my xorg.conf is causing the spam of flip errors in Xorg.0.log


Section "Monitor"
        Identifier      "Denon-AVAMP"
--->    #Option         "Enable"        "true"   <----
        Modeline        "1920x1080" 148.50 1920 2008 2052 2200 1080 1084 1089
1125 +hsync +vsync
EndSection


if "Option Enable true" in the monitor section is commented out, then there is
no log spam
this is a left over to force the hdmi-output to 1920x1080 with the Denon-AVAMP
off ... but i had no luck

So this was a configuration error and can be resolved as not a bug?

imho .. spam the log with flip errors, when set this option should not happen
the Xorg.0.log was some days about 80MB big
bit, feel free ... it's up to you

I have found this issue today at FOSDEM after disconnecting the VGA cable from
the projector (not sure if before or after putting the computer to sleep).

When I came back, this wasw happening and xrandr showed what follows:
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
   1366x768       59.9*+
   1280x720       59.9  
   1152x768       59.8  
   1024x768       59.9  
   800x600        59.9  
   848x480        59.7  
   720x480        59.7  
   640x480        59.4  
HDMI-0 disconnected (normal left inverted right x axis y axis)
VGA-0 disconnected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm
x 0mm
  1024x768 (0x6c77)   65.0MHz
        h: width  1024 start 1048 end 1184 total 1344 skew    0 clock   48.4KHz
        v: height  768 start  771 end  777 total  806           clock   60.0Hz

After running xrandr --output VGA-0 --off to turn VGA off it worked again.
