Also according to the dmesg you sent suspend didn't even start, so I guess you're seeing a separate issue. Maybe the lid notification isn't properly handled, but I can't really help tracking that down. In any case to reproduce the particular bug in question (or see if the fix works) you need to get the machine to suspend/resume somehow. One way is to 'echo mem > /sys/power/state' as root and resume by pressing power button or similar; could you still try this, again sending the dmesg?
