[2.6.13+swsusp2] iounmap Oops

[Emmanuel Fleury]

Hi all,

I have a Debian unstable (Xorg) and recently (since I installed the
2.6.13) I've noticed a new message in /var/log/kern/log:

Sep  5 08:39:21 hermes vmunix: iounmap: bad address d72f2000

Seems to be linked to the DRM of the Radeon driver, but I ain't no
expert. If wanted I can dig a bit more.

Looks like mine, can you send me your /var/log/Xorg.0.log and xorg.conf, 

And if you have a chance can you 
echo 1 > /sys/module/drm/parameters/debug and reproduce and send me dmesg...

Dave.
