My Dell M101z with a Radeon HD 4225 fails to resume from suspend when my HDMI monitor is connected when I run s2ram. If the monitor is connected on resume I have to run xrandr a couple of times to get video on the monitor again. I also have to boot with the noapic option in order for resume to work at all.
