Okay, I was asking you to actually provide that data, Reindl. ;)

Yep. My laptop (Lenovo Thinkpad W510+) goes from suspend to running in a
few seconds. Hibernate's been broken in F17 for me so no stats there ATM
(which is why I'm interested in this thread).

Not so quickly for me. Granted my swap and home partitions are
encrypted, but the password entry is hard a second or two during the
boot process.

Still, that's an issue separate from hibernating or suspending a
machine that should be handled similar to any other network interruption
scenario.
