[Bug 31527] Re: DRI locks up the machine when starting X on a Radeon 9250

[Christian Dröge]

I have the same issue with:
 * Dapper with a current kernel (linux-image-2.6.15-21-amd64-k8) running on 64 bit
 * Radeon 9250 with 128 MB from Powercolor
 * Asus K8V Deluxe mainboard (K8T800, amd64...)

Everything works well until I activate DRI in the module section in the xorg.conf. Maybe there is something helpful in my Xorg.0.log after activating DRI... (-> http://draugr.de/Xorg.0.log). The fix posted by ath in the second comment didn't help here... but within the next few days I will try a drm snapshot...

After modprobing drm and radeon (the official ones) dmesg says nothing about the card (it should):
