It means there's a race condition. There are two drivers, one in X, one
in the kernel. He's suggesting the kernel driver is taking so long to
load that the X driver is going ahead and loading without it. When the
X driver does this, it does not enable kms support (since by definition

Hi Bryce,
No, don't think it booted correctly. I'm quoting from the attached
dmesg.txt:
[ 28.810665] [drm] Driver supports precise vblank timestamp query.
[ 28.810673] radeon :01:00.0: Fatal error during GPU init
[ 28.810683] [drm] radeon: finishing device.
[ 28.810688] [TTM] Memory
Ah, looks like that cleaned up the error. Did it boot the radeon driver
properly and get you to a working session after that?
If so, I'm going to guess this is another module-init-tools bug / race
condition with loading the drivers.

vesa ON, and rebooted. Here is output of dmesg.

Thanks Alex. Does this mean that Natty grub load sequence needs to be
sorted out?
I'm not very experienced with linux, and I haven't had the time to play
with the grub sequence. I did notice that /etc/grub/grub.cfg calls
things like gfxterm, which presumably is some sort of X related process?

Title:
Radeon 7000VE (rv100) fatal error during GPU
On irc, a user suggested to turn off KMS by creating /etc/modprobe.d
/radeon-kms.conf with the line options radeon modeset=0 (no quote).
That got me passed the problem. Now I get direct rendering: Yes

The problem is the drm is being loaded after X starts, so you end up
with the ddx in ums mode while the drm is in kms mode. For kms, the drm
needs to be loaded before X starts.
