/dev/mapper/cryptswap1 errors and not booting

[Adam Smith]

Binary package hint: cryptsetup

Basically every boot in ubuntu studio the system has a 50% chance to crash, while usplash is running, it will scroll under the boot splash complaining about /dev/mapper/cryptswap1 in /etc/fstab, then it might freeze at the boot splash, get to gdm and black screen, or it just might boot. Here is my fstab: http://pastebin.com/f7a64777f

system info:
dual boot ubuntu/vista
fresh install of ubuntu-studio x64 and all updates
compaq cq60-215dx laptop
nvidia 8200M G
4 gigs of ram
