Hi Michel, and others,

I believe the patch from the bug id=66425, mentioned earlier in the
thread, seems to be part of upstream

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9cc2e0e9f13315559c85c9f99f141e420967c955

and unsurprisingly the version of the change in Linus's git compiles
without issues. Unfortunately the 3.11-rc2 does not fix my suspend
problem/resume problem. Let me know if I can some how help you to
debug this issue.
