--- Comment #5 from Arthur Marsh arthur.marsh@internode.on.net --- Created attachment 113009 --> https://bugs.freedesktop.org/attachment.cgi?id=113009&action=edit dmesg after patches applied and with radeon.test=1
After applying the patches and rebuilding the kernel and booting with radeon.test=1 I had the problems shown in the dmesg output and video output not working until I rebooted again.
