Subject: Resume from hibernation fails 40% of time, kernel 3.16.0 (64GB of
 RAM, 32 Xeon E5-2687W cores)

Hi,

I have an up-to-date recently installed debian wheezy. I downloaded
https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.16.tar.xz and compiled it using:

  cp /boot/config-`uname -r` ./.config
  make menuconfig
  fakeroot make-kpkg --initrd --append-to-version=-vanilla.1 kernel_image kernel_headers -j38
  dpkg -i linux-image-3.16.0-vanilla.1_3.16.0-vanilla.1-10.00.Custom_amd64.deb linux-headers-3.16.0-vanilla.1_3.16.0-vanilla.1-10.00.Custom_amd64.deb

where .config was taken from debian /boot/config-3.14-0.bpo.1-amd64

my PC has 64GB of RAM, 32 Xeon E5-2687W cores and motherboard SuperMicro MBD-X9DRI

I just did 25 tries of suspend/resume cycle. I tried 4 different
methods of hibernation, you will find a full summary of my tries
(including how many failures for each method) in attached script
SLEEP.sh which I always used to perform hibernation.

The failure was always a reboot after resume had almost succeeded. In
cases when there was a success there was a ---[cut here]--- part
which is in the attachment. All of my successes are included in the
attachments (please note that method had 0 success rate, so no
success logs are attached for it).

I post here to get your help, and my first question: how can I
retrieve some useful logs from a failed resume attempt?

best regards
