The Xorg.0.log

When I start X the machine halts, the screen goes blank, only a hard
reboot makes anything new happen.  No log records any error.  The i915
module loads, but the problem happens without it.

I built xf86-video-intel and libdrm from tarballs that I downloaded 2010 March 15 and still have the same problem, producing the same Xorg.0.log.

I welcome debugging hints.

I scheduled a shutdown in 2 minutes, then started X.  The scheduled shutdown happened.  So it would appear that keyboard input is being ignored (I can't be sure about mouse input) and nothing displays.

If a scheduled shutdown works, you can probably also log in to the target machine and figure out where X is hanging.  You can try attaching to it with gdb and/or doing 'cat /proc/`pidof Xorg`/wchan (or `pidof X` if that's how you're calling it).

The X log stops right where we first access the framebuffer, which means something is pretty seriously wrong...  Can you also attach your dmesg?

Any update here?  Hopefully it was just an old bug that's been fixed in more recent kernels and libdrm...
