Description Jarod Wilson 2009-06-24 19:16:34 EDT
Description of problem:
I no longer get video output when booting kernel 2.6.31-0.24.rc0.git18.fc12.x86_64 in a box equipped with a radeon x1300 pci-e video card. Video disappears pretty quickly, and dmesg gets filled with repeating error messages.

Version-Release number of selected component (if applicable):
kernel-2.6.31-0.24.rc0.git18.fc12.x86_64
xorg-x11-drv-ati-6.12.2-18.fc12.x86_64

The Forbidden/ERROR pair repeats ad infinitum, once per minute after the initial round of spew.
