Hello, On a T440s (intel graphic + nvidia) with ubuntu 16.04, I experience random freezes when waking up from hibernation.
Suspend to ram works fine. But when waking up from suspend to disk, it happens that either the screen go black and the system becomes totally unresponsive, or the system actually wakes up but freezes soon after, in this latter case, I can see in the log a "general protection fault" followed by what seems to be a kernel crash (can post it if you want). But sometimes, it runs just well, it is quite random. I suspect some kind of race conditions, but it always happens if I hibernate/wakes up more than 3/4 times one after the other. >From the logs, I cannot infer what is going on. It also happened with ubuntu 14.04 but much more rarely. When installing ubuntu 16.04, I had to put the wifi module in the SUSPEND_MODULE list for the hibernation to work (crashes every time otherwise). Putting more modules (bluetooth, bbswitch) did not solve the issue. Could you help me in solving this bug ? What should I do ? Thanks in advance for your attention.
