[HELP (not patch)] Re: Resume from hibernation fails 40% of time, kernel 3.16.0 (64GB of RAM, 32 Xeon E5-2687W cores)

[Janek Kozicki <janek_listy@wp.pl>]

I see that this list is extremely busy, I thought this is the
place to go asking for help in debugging hibernation. If that's not
the right place, please tell me where should I go. If that's the
right place, please get me started. First - how can I retrieve some
useful logs from failed resume attempts?

(details in my previous email)

best regards
