Comment # 2 on bug 89177 from eduardo

I wonder why this bug is still open, I have been having this random behavior on
kernel 3.18 and 3.19 since they came out, sometimes the pc starts properly, but
other times I start my laptop and then just appear a black screen and nothing
else happens, so Im stuck in kernel 3.16, and seems to be I will be there for a
while. This bug should have a higher priority to be fixed.
I use an amd cpu, amd gpu (mobility radeon hd 4200), r600 free driver, if that
somehow matters.
