I found upgrading to the latest kernel on linux mint lead to my zfsonlinux modules not being rebuilt through dkms like it should and normally does. Found this thread on google groups.
As ypu can see, my succinct solution was:
dkms install -m spl/0.6.0.97 -k 3.2.0-38-generic/x86_64 dkms install -m zfs/0.6.0.97 -k 3.2.0-38-generic/x86_64 update-initramfs
