This is almost identical to the log from 3.2.54-2, except some crypto modules aren't loaded (cryptd, aes_x86_64, aes_generic). So it seems like the resume is mostly successful. As you say the screen remains blank, that suggests a regression in either the GPU (radeon) or backlight driver. For some reason, your bug report didn't include information about the GPU; can you send the output of 'lspci -vnn' please? Ben. -- Ben Hutchings Sturgeon's Law: Ninety percent of everything is crap.
