On my laptop hibernating with the Ubuntu kernel means sitting for
about 15 minutes in front of a blank screen hoping it's not crashed and
no possibility to cancel. Actually it was the first time now I did a
full hibernation cycle with the Ubuntu kernel as I just did a power-off
when it wasn't ready after 5 minutes when I tried it first after
installing Dapper. Is it worth a bug report?
Hibernating with suspend2 means waiting 55 seconds seeing a progress bar
with some messages what it is doing now and the possibility to press
<Esc> to cancel hibernation.
