Hi, when changing the refresh rate of my laptop display with xrandr on 3.11.0-rc5, like: xrandr --output LVDS1 --rate 59.9 --mode 1920x1080 The following WARNING is generated: [ 50.018055] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode.flags (expected 1, found 0) [ 50.018060] ------------[ cut here ]------------ [ 50.018105] WARNING: CPU: 0 PID: 1819 at /home/arnd/Projekte/kernel/linux-2.6/drivers/gpu/drm/i915/intel_display.c:8286 check_crtc_state+0x59f/0xa30 [i915]() [ 50.018106] pipe state doesn't match!

The update of the refresh rate seems to work nevertheless, though.
