--- Comment #3 from Harald Judt <h.judt at gmx.at> ---
Update: I've tried finding out where troubles started. 3.13.11 works fine, the
next version I tested was 3.14.9. I haven't seen any corruptions yet, but there
is one major problem: Most times, resuming from hibernation won't work and will
end in a black screen. This same? issue happens with 3.15.2, although much more
rarely, but I believe it is still there. tuxonice has a nifty feature here
which will allow you to try to resume from the same image. After two or three
tries, this usually works. So to sum up:

3.13.11 usually works fine
3.14.9  works somehow, but you'll get your share of black screens and several
attempts to resume in a row to get your working session back
3.15.2  only sometimes has the same issue as 3.14.9, but introduces other
issues like gpu hangs and corruptions and sometimes freezes on hibernation

Maybe I can do a bisect of 3.13 and 3.14 or 3.14 and 3.15 but there have been
quite a few stability issues in 3.14 that make this process tedious and
difficult.
