This message clearly does not apply directly to all subscribers to this bug, because some have NVidia graphics. However I noticed that I had an error in dmesg "[drm:rs400_gart_adjust_size] *ERROR* Forcing to 32M GART size (because of ASIC bug ?)" and that this is solved in Bug #562843 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/562843

The solution to Bug #562843 is to add "radeon.modeset=0" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and then run sudo update-grub2.

I have repeatedly suspended and resumed, by closing the lid and from the menu, without a single failure to resume since applying this boot option. (That may be just luck - I will post when my system freezes or fails to resume).
