Rebooting into 2.6.28-4-powerpc (or pretty much any previous kernel) results in a working system again, no log messages and working 3D. This is newly introduced in 2.6.28-5-powerpc.

Forwarded from Ubuntu bug https:/ /bugs.launchpad .net/bugs/ 345542
DRM fails to initialize on PowerPC with Ubuntu kernel 2.6.28-5-powerpc, based on 2.6.28.1 (the 2.6.28-4-powerpc, based on 2.6.28, worked fine).
[drm:radeon_ do_init_ cp] *ERROR* could not find ioremap agp regions!
Unlike the problem with 2.6.29 reported earlier (http:// bugzilla. kernel. org/show_ bug.cgi? id=12441), "nopat" does not help.
The original reporters will also try newer kernels or build newer drm modules, but the reduced support for PowerPC in Ubuntu makes it more challenging.
