I've attempted to troubleshoot the issue by following the wiki at
https://wiki.ubuntu.com/DebuggingKernelSuspend

After following the steps there I got the following clues in my dmesg output:
[ 0.487733] PM: Resume from disk failed.
[ 0.487752] registered taskstats version 1

If I interpret the dmesg output correctly, the relevant offender is the video card:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)

I've tried blacklisting the radeon module but that appears impossible at the moment (it loads anyway).
I then added it to the suspend modules list it in /etc/pm/config.d/config but that didn't do anything.
