Strangely the preceding commit works well, so I bisected the kernel
again, this time more carefully and I've got a different result!
(see bisect_log attachement).
It seems to be commit 73201dbec64aebf6b0dca855b523f437972dc7bb 
(https://patchwork.kernel.org/patch/1511921/).
Someone on LKML already reported an issue with this commit
(https://lkml.org/lkml/2012/10/18/228) , but Peter
Anvins patch got already applied in newer versions.
Reverting this patch with the recent git clone seems to be difficult
because it already has too much dependencies.

Additionally I've included dmesg dumps of the last good and the bad
kernel version.

It affects really all versions after that commit and the failure happens
every time I try to resume my notebook.

Best regards,
