I have the same problem with this kernel on three different ATI graphics
systems. There is a kernel oops, as stated, followed by very slow graphics.
The kernel has a bug (probably Radeon DRM). I have gone back to
2.6.32.14-127.fc12.i686.PAE (By editing /etc/grub.conf) and all is well
again. Have reported bug via the abrt system.
