Should be safe, but the machine can be resumed and it will run with all
encrypted partions mounted and networking enabled, which might give
some chance to break in.

You could also use suspend to disk to an encrypted device. I use
dm-crypt, newer versions of suspend2 also have native encryption
support via the crypto-API of the Linux kernel. This way, even after
resume from suspend a password is needed to get the machine back to
life.
