[SOLVED] kms for intel does not recognize hdmi/displayport

Hi,

I updated yesterday my laptop, which has a intel gpu coming with the Core-I5 chipset (not the HD one).
With the new kernel 3.6.10, it does not detect any hdmi/displayport ouput anymore. VGA and LVDS are just fine and also the modes which are detected are correct.

First difference is also, that when the external hdmi display is connected also during startup, usually the framebuffer is visible on both LVDS and HDMI but not anymore.

The log output does not look too bad:

$> dmesg | grep fb
[    0.511013] vesafb: mode is 1280x800x32, linelength=5120, pages=0
[    0.511015] vesafb: scrolling: redraw
[    0.511016] vesafb: Truecolor: size=8:8:8:8, shift=24:16:8:0
[    0.511618] vesafb: framebuffer at 0xd0000000, mapped to 0xffffc90011000000, using 4032k, total 4032k

$> xrandr

   1024x768       60.0 
   800x600        60.3     56.2 
   640x480        59.9 
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 521mm x 293mm
   1920x1080      60.0*+
   1680x1050      60.0 
[...]

Any help would be greatly appreciated, also please let me know if you need more info.

SOLVED: This is now solved with kernel 3.6.11

Thanks,
Johannes
