I'm running Ubuntu 13.10 on a MacBookPro9,1. On this machine I can't resume after a suspend: the desktop background (sometimes) appears but the system is unresponsive, and switching virtual terminals might or might not work.
I believe this is not a duplicate of bug #817017 (AHCI mode not restored during sleep-wakeup cycle). I am booting using EFI, and as described on that bug page the AHCI bug does not occur on EFI systems. In fact, originally I was not using EFI to boot, and I saw the symptoms on that page (the display was completely blank when I tried to resume). Then I switched to EFI and the symptoms changed (I saw some stuff on the display but the system was unresponsive). So I conclude that this is a separate bug.
