dmesg log of radeon errors

I have an ASRock A75M motherboard with an A8-3850.

Booting a 3.1 kernel (also tried 3.06), my screen goes blank with
modesetting enabled. If I disable modesetting, I am able to boot fine
but then X won't work because the X11 driver requires modesetting.

The problem is happening right at boot. With DRM_RADEON_KMS enabled in
my kernel config, the screen goes black immediately after exiting the
bootloader. The machines is not wedged because <ctrl-alt-delete> still
works.

If recompile with DRM_RADEON_KMS=n, the screen goes black (for longer
than I'm used to) but then I see the kernel printks and then a login
prompt. When I try to run X with xf86-video-ati I get an error message
telling me that SUMO requires KMS. So I'm currently working around by
running with the VESA X drivers.

This is a brand new machine which I just brought up yesterday. Windows
seems to work fine so I don't think its a hardware issue.

The motherboard comes with a VGA and an HDMI connector. I'm currently
using the VGA connector.

I probably should have assigned this to Product:DRI instead Product:xorg
since the problem I'm seeing is in the kernel driver and not in the xorg
driver.

The DP to VGA bridge chips on a llano APUs are problematic in a lot of
cases.  You might try a newer kernel or use a digital port (HDMI, DP,
DVI) in the meantime.

Is there a radeon linux kernel tree I could test? I'm also happy to test
any patches against any tree.

I've ordered an HDMI-DVI cable so I'll give that a shot in a few days.

You can try drm-fixes-staging, but I doubt you'll see any change.  I'll
be sure to update this bug as I make progress with the NUTMEG chip.
