--- Comment #19 from StephenH <hafflys at earthlink.net> ---
Fedora kernel 3.15.x versions on an Acer Aspire One netbook with AMD C50
processor and Radeon driver has this problem.
Kernel 3.14.x and earlier kernel versions did not have this problem.

Whatever changed between 3.14.x and 3.15.x has caused this problem. I have a
bug report at https://bugzilla.redhat.com/show_bug.cgi?id=1121838 but I think
the problem will need to be addressed here, upstream from Fedora.

Kernels 3.14 and under = work fine.
Kernels 3.15.x != work

I asked in the buzilla report cited above what changed that could cause this
and how do I fix it? With Fedora working to rebase Fedora 20 to 3.16.x, if the
problem has not been fixed, then there will be problems. This will be even more
so when Fedora 21 is released and Fedora 19 becomes an E.O.L. version. I am
currently running Fedora 20, but I have to use a Fedora 19 kernel
(3.14.17-100.fc19.x86_64) in order to have suspend/resume work properly.

Please don't ask me to bisect unless you give me explicit directions on how to
do so. I have no idea what bisecting does or how to do it. I'm not a developer.
