Created attachment 140147 Xorg.0.log with modeset error

I am using an Intel Ivybridge Mobile laptop with the git version of xserver.

When Option "PageFlip" is enabled (which is by default)I get the following repeated error in xorg.log:

(EE) modeset(0): Failed to get GBM bo for flip to new front. (EE) modeset(0): present flip failed

No such errors when page flipping is disabled in xorg.conf.

Same issue when using xorg-server-1.20.0.

Please see the attached xorg.log.
