I started the system with drm.debug=0xe with the same effect - therefore I was not able to log in %-( Btw. when starting into single user mode, I was able to say 'xinit' which produced the borderless xterm at the top left position. So obviously the display is working. Running lightdm from the console in single user mode does not work (dbus missing?). Starting lightdm a second time kills the console. I think I need to dig into the lightdm and startup stuff. So this might not be an i915 issue. Sorry for the noise. I'll send an update if I discover any new info ...

Thanks for reporting back, I'm glad it works for you now. However, for closure, I would appreciate it if you could do a reverse bisect to find out which commit fixed things for you.

I checked the 'x86/urgent' patches which talk about some major glibc breakage that have been fixed in that pull request. So I just reverted the patches form the 'drm-fixes' to make sure that my problem was not introduced by the i915/drm stuff. It finally made do difference whether the last 'drm-fixes' where applied or not. It obviously was the glibc issue for x32 which killed my lightdm/xfce4 startup.
