Hi,

since I've updated on my thinkpad x200s to latest Linus' tree (3235031), I
am getting a lot of

[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 21: Can't calculate constants, dotclock = 0!

googling revealed this patch:

http://permalink.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/67471

is there any reason why it's not present upstream?

Thanks,
