I just tried 3.2.20-28.44 from pre-proposed. It booted fine. I connected to my VPN and started up my softphone. Shortly after that, I had the kind of freeze where all applications froze (second hand on clock stopped) but mouse movement still worked. Magic SysRq did work to safely reboot. When I booted back into 3.5.0-4.4 and checked syslog, I noticed several of these lines, which I assume indicate something related to the freeze:
