there's no need for this on X.org bugs, the Xorg.0.log file contains
sufficient information on the graphics hardware.
This bug seems to be both a KMS bug and a Xorg bug. I can get boot into
runlevel 3 but the display isn't initialized properly and the only way I
got some of the debug information attached to the bug was by blindly
logging in, setting up sshd and then logging in from another machine.
The second problem is that when I boot with nomodeset I get to the desktop
but it is so slow it cannot be used for regular work. I'm not sure if that
is a bug or because the radeon driver now requires KMS for any sort of 2D
acceleration.
On most radeons, both UMS and KMS are accelerated on Fedora 12.
That may not be the case for R700, and at any rate we'd rather have
the KMS codepath working than the older UMS.
If booting into KMS/runlevel 3 fails, it's a KMS problem, Xorg has no
way to recover from that.
On the other hand, your logs show both nouveau and radeon, as pointed
out by Jóhann. Could you try booting with the parameter:
nouveau.modeset=0
and report?
Success! Adding "nouveau.modeset=0" did the trick and the machine now boots
into runlevels 3 and 5 with the displays native resolution of 1920x1200.
Two things though:
1. During boot I just got the same boring old progress bar at the bottom
that I also get on F11. Aren't I supposed to see a funky boot plugin with KMS?
2. While the performance is not as unusable as it was with "nomodeset" It's
still a lot worse compared to F11. I can barely play a youtube video. (eats
one of my two cpu cores almost completely whereas on F11 that takes about
15% in "top")
