Ideally you could use git to bisect between 3.6 and 3.7 to see what c

Hmm. Just noticed that that one kernel version number says "config" at the
start instead of "kernel". That's because I got the version number from the
config file in /boot.

OK, another report. First, when it locks up, there is no ssh access possible;
it doesn't even ping.
Second, I've narrowed it down this far:
Working: kernel-debug-3.6.11-3.fc18.x86_64
Not working: config-3.

OK, I've narrowed it down quite a bit.
The kernel which Fedora (18) calls kernel-debug-3.6.10-4.fc18.x86_64 works.
Xorg segfaults, but the radeon module successfully loads. The kernel which

Anyway, it looks like I was wrong about the kernel modesetting; I think this is
a side-effect of the more modern radeon driver not supporting nomodeset. So
it's just a bug in the radeon driver, pure and simple.

Just reporting back; blacklisting radeon as Alex specifies allows the machine
to boot. "modprobe radeon" after boot makes it die. Unfortunately I only had
a little time to put into it, so that's all my results

--- Comment #4 from Alex Deucher ---
Can you also try blacklisting radeon and loading it after the box has booted
and you have remote access? E.g., append modprobe.blacklist=radeon 3 to the
kernel command line in grub (the 3 is to boot into run

Well the nomodeset option only makes sense with the UMS support and that was
deprecated in January 2013.
So as long as Fedora 20 doesn't compile their kernels with a deprecated feature
they probably won't

Regarding "not worked", these kernels have always hung on boot with a blank
screen; most of these are from my attempts to upgrade to various different
versions of Fedora between 13 (currently working for me) and

--- Comment #1 from Alex Deucher ---
Can you elaborate on what "not worked" means? Blank screen, corruption, hangs?
Are you able to access the machine remotely? If so, can you attach your xorg
log and dmesg output with the radeon driver loaded
