Well, that patch (it’s for kernel 2.6.31) just turns that error message into a debug message.
In Kernel 3.11 this is only a debug message anyway.
The corresponding code there:
DRM_DEBUG_DRIVER("trying to get vblank count for disabled "
The message seems to point to a possible “bug” or flaw in the intel driver, you might try the latest version from the [noparse]X11:XOrg[/noparse] repo. (you have to do a Full repository Vendor change update to that repo though, as the driver from that repo will not work with the Xorg from openSUSE 13.1.
But why do you care about this message at all, if everything is working as expected? Just ignore it in this case, it’s only a debug message anyway.
