2560x1440 platform FIFO underrun error

[arm_lover]

  When the system run at 2560x1440 distribution, the screen would go blank on Cherry Hill(Intel I915) platform. But the platform works well on windows system.
  The system start normally in X-windows-disabled, then I switch to X Windows, the screen will go blank.

command: dmesg | grep drm
output: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
