2015020917dmesg.txt behaviour when booting with radeon.test=1 with 3.19 kernel and 3850hd
I tried booting with the 3.19 kernel and radeon.test=1 and had to restart afterwards to restore video output.
Arthur, there's no need to keep posting the same information as long as the behaviour doesn't change.
Where to from here? I'm happy to build kernels and other packages from source, test and bisect, but I'm not a C programmer.
