Forwarding this bug from Ubuntu reporter Alexander Hunziker:

Screen corruption shown on resume when using KMS from the radeon-rewrite branch

libdrm - 2.4.12+git20090806.d74c67fb-0ubuntu1 
linux - 2.6.31-6.25~radeon2

[Original Description]
When using the new ATI stack from the X-swat PPA (radeon-rewrite with DRI2 and KMS), suspend is broken on my Thinkpad T60 with ATI Mobile X1400. After waking up the system shows colorful vertical bars on screen. I'll attach a screenshot of that as soon as I can.

Also, dmesg is full of the following messages:

[ 9315.666488] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(7).
[ 9315.666491] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !

Screenshot during shutdown

On the first screenshot attached, one can see a square that moves when I move the mouse pointer.

After "blindly" shutting down the machine, the screen turns orange (presumable because of the Ubuntu usplash being orange), see second screenshot.

Seeing this problem also on a T60 with a M52.

It's not LVDS specific, and the same corruption also occurs on externally connected monitors.

Also, the corruption actually happens before kernel finishes suspending. On suspend-to-disk, corruption is triggered around the time kernel starts writing the image to disk.

Appears to be a Thinkpad-specific BIOS quirk.

Duplicate of #23273 ?
Comment 5 Jörg Mayer 2009-08-24 07:56:38 UTC
Yes, the pictures look very familiar :-)
Note that I do not see the bars before suspend - but as my system currently doesn't support suspend-to-disk, I can't verify whether that's a suspend-to-disk vs. suspend-to-ram thing.
Comment 6 Jörg Mayer 2009-08-24 08:01:32 UTC
I probably should have mentioned that I opened bug 23479 about that. That bug also contains the logs that come up during resume.
Comment 7 Tom Morton 2009-09-02 06:15:24 UTC
Can confirm seeing this on my Thinkpad T60 with radeon x1300 mobile.

Corruption just as in those screenshots. System still 'up' (I can switch VT and see different garbled corruption patterns, and do ctrl-alt-delete to initiate restart)

Same problem here with 2.6.31 kernel, xorg-server and radeon driver from git (as of today). Kernel commandline option "nomodeset" is a workaround for me, so the problem is obviously KMS related.
Comment 9 Silvio Frischknecht 2009-10-10 06:44:46 UTC
I was just wondering could it be that this is a 64-bit problem? Or are there also people around who experience this with a 32-bit kernel?
Comment 10 Alexander Hunziker 2009-10-10 07:18:34 UTC
I'm on 32 bit
Comment 11 David Kiliani 2009-10-13 04:31:51 UTC
I just checked out the vanilla 2.6.32-rc4 kernel with the KMS initialization path changes and the bug still occurs. I'm also on 32bit here.
Comment 12 Tom Morton 2009-10-13 07:23:07 UTC
Is everyone who sees this bug on a Thinkpad T60?
Comment 13 David Kiliani 2009-10-13 07:32:13 UTC
Thinkpad T60 with ATI X1400 here.

Is it possible / helpful to supply any additional data, like logs or memory dumps?

eading http://airlied.livejournal.com/68550.html from 
describes how the bug was fixed.
Link to the fix:
The bug can also be found in redhats bugzilla:
where it is marked as fixed. Unfortunately that is not where non-redhat/fedora
users would look :-(

I can confirm that this fixes my problem.
Not closing it yet as it isn't part of the kernel.org sources yet.
