Since you reported the bug, drm-intel-next got some fixes related to eDP. Please retest. The updated drm-intel-next still doesn't work. Created attachment 52981 [details]
dmesg with drm.debug=0x0e

I've pushed an 'ivb-edp' branch to fdo that has this patch (and lots of other stuff). Thanks, Keith. Using the patch, EDP still doesn't work, and kernel crashes. I see below commit in drm-intel-fixes (but not in -next). Xun, can you verify this bug with -fixes? author Keith Packard <keithp@keithp.com> 2011-11-17 00:26:07 (GMT) committer Keith Packard <keithp@keithp.com> 2011-11-23 21:07:12 (GMT) commit 1a2eb4604b85c5efb343da8a4dcf41288fcfca85 (patch) (side-by-side diff) drm/i915: Hook up Ivybridge eDP The Ivybridge eDP control register looks like a cross between a Cougarpoint PCH DP control register and a Sandybridge eDP control register. Where things trivially match, share the code. Where there are any tricky bits, just split things out into two obviously separate code paths.
