Christophe, the next step is to fully reverse commit bisect from kernel 3.2 to 3.18 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting.
Thank you for your understanding.

It is a samsung n220 netbook, with ubuntu 12.04 precise and 3.2 kernel. When the system hangs on wake, and I try to hit the caps lock key, the led does not light up, meaning (I think) that it's not a problem of video card, but a real kernel hang. It happens 1 over 5 times when I make my suspend my system to ram. WORKAROUND: intel_idle.max_state=0 or 3 kernel parameter, but the battery discharge rate shown by ubuntu is increased by at least ~1W. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
