Hi, sorry for hijacking this thread, but apparently my other plead
for help got ignored in this very busy mailing list.

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:

1. /usr/sbin/hibernate                  # 7 successess, 1 failure
2. /usr/sbin/s2disk                     # 8 successess, 2 failures
3. echo platform > /sys/power/disk      # 0 successess, 5 failures
   echo disk > /sys/power/state
4. echo shutdown > /sys/power/disk      # 2 successess, 3 failures
   echo disk > /sys/power/state



The failure was always a reboot after resume had almost succeeded. In
cases when there was a success there was a following ---[cut here]--- part:

To start debugging this my first question is: how can I
retrieve some useful logs from a failed resume attempt?

best regards
