[Intel-gfx] X201 + i915 pll problem

[Dave Airlie]

Has anyone seen and/or fixed:

[drm:drm_mode_debug_printmodeline], Modeline 12:"1280x800" 60 68940
1280 1296 1344 1408 800 801 804 816 0x48 0xa
[drm:ironlake_crtc_dpms], crtc 1 dpms off
[drm:ironlake_crtc_dpms], crtc 1 is disabled
[drm:intel_crtc_mode_set], using SSC reference clock of 120 MHz
[drm:intel_crtc_mode_set] *ERROR* Couldn't find PLL settings for mode!
[drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on crtc
ffff88022e4ff000
fbcon_init: detected unhandled fb_set_par error, error code -22

Its an Arrandale X201, I have one with a slightly different panel and
it seems fine, this one another person has doesn't.
