It's not rbd per se. Those kernels are probably just missing
a backport. Kernel 3.13 wasn't a regular LTS, so even though ubuntu
team generally does a good job and applies a lot of patches, something
may have been missed.
Can you try upgrading the kernel package and booting with 512M, just to
confirm?
Thanks,
Ilya
