Title:
freeze on wake from suspend on 16.04, Dell Latitude e7470
Status in linux package in Ubuntu:
Expired
Bug description:
On waking up from suspend, the display stays black. I cannot switch to
the console, nor kill the x server. After a while the laptop reboots
itself, or alternatively, I power it off.
It does not happen on every suspend, but very often. I happens most of
the times when the laptop was recently connected to the Dell dock,
which connects to an external display via DVI and ethernet.
My system is Ubuntu 16.04 with all updates, kernel Ubuntu
4.4.0-34.53-generic 4.4.15 on a Dell Latitude E7470. FDE is enabled,
swap is on the encrypted partition.
I've tried a 4.6 kernel from mainline-builds, that did not solve the
problem.
I'd be very grateful for any advise on what to do about this.
