Comment 4 for bug 1566302

Yes, the issue start happening after update to 4.4.0-16 on 5/04/2016 (morning update). The problem did not happened with 4.4.0-15.

I tested uptream kernels 4.5 and 4.6 and I didn't have the freeze after suspend. Actually, yesterday night (5/04/2016) there was another ubuntu update (including kernel update to 4.4.0-17) and I can confirm that the bug seems to be fixed also for 4.4

I then booted again with the supposedly buggy kernel 4.4.0-16, and I couldn't replicate the bug, so my guess is that the bug reason was not actually in the kernel, but due to some other package.

So: the bug seems to be fixed with the ubuntu distribution as of yesterday night (kernel 4.4.0-16 and whatever additional updated packages). Also fixed for 4.5 and 4.6.

Thanks for your time and great work!
