Well, like said, there are known drm/ttm/kms related problems in
Jeremy's tree atm.

I think I got it working with this (temporary) patch:

I've just applied suggested patch to the most recent clone of Jeremy's tree and rebuilt
the JF's 2.6.31.6 kernel. Same error :-

I guess this is some other problem then.. you might want to enable more
debugging options for drm to see what actually goes wrong.

Basicly you should extract the initrd image, and change the "modprobe drm"
line to say "modprobe drm debug=255" in the init script. And then
repack the initrd and use the modified initrd instead.

Does it work with "nomodeset" btw?

Jeremy's kernel works either ways..
It just reports error and disable ksm.
Michael's kernel starts loading with "nomodeset" option.

Michael's kernel rpms are based on Fedora kernel rpms, so they contain
various drm/graphics related patches that are not yet upstream.

That could be the reason.

debugging options for drm to see what actually goes wrong.

Basicly you should extract the initrd image, and change the "modprobe drm"
line to say "modprobe drm debug=255" in the init script. And then
repack the initrd and use the modified initrd instead.

Does it work with "nomodeset" btw?

Hmm.. isn't this the same output as earlier? Are you sure you used the
new initrd? It doesn't look like it..

You should get much more debug information from drm when it's loaded
with debug=255.

Example here:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/radeondebug/dmesg-2.6.31.4-20...

do "grep -i drm dmesg-2.6.31.4-2009-10-21-with-ttm-patch.txt" and you'll
notice there is a lot more debug information..

Reports are different  it's easy to see,  but not much.
I put in init :-  
    modprobe drm debug=255
and rebuilt initrd . It's for sure.
Maybe change some other lines ?

Boris.

Hmm.. maybe the 'radeon' module needs some debug parameter aswell?

You could check the radeon module source from the kernel, and figure out
if it has some debug option aswell.. and then enable it.

Then again there is a lot going on with drm/kms/radeon stuff at the
moment, so I'm not surprised if it happens to be broken in 2.6.31.6.

Does it work if you boot the same Jeremy's 2.6.31.6 on baremetal without
Xen?
