dmesg with dri.debug=4
I have a behaviour very similar to

bz_status_NEW "
title="NEW --- - Display does not work when resuming from suspend"
href="show_bug.cgi?id=42960">https://bugs.freedesktop.org/show_bug.cgi?id=42960</a>.
After resuming from suspend, display is blank.
I have tried the tricks suggested in #42960 (acpi_sleep=s3_bios) with no luck,
when I use that the laptop doesn't resume correctly.
With the catalyst driver the display resumes correctly.
It's an Ubuntu 13.10 with a 3.14 kernel, DPM is activated.
Feel free to ask for tests.</pre>
