Matthew Garrett developed a patch to make Linux's ASPM support match

This should offer power savings and would match Windows behavior.

The system is a Dell Precision M3800 Developer Edition, i.e. it has

Utopic HWE versions, the touchscreen doesn't work. *However*, if I
suspend and resume, the touchscreen starts working again.

Awesome, I see that installing the HWE Xorg also removes gnome-control-

I've some quick suggestions from my colleague Narendra here at Dell to
pass on. First try disabling TSO. If that doesn't work, disable both GSO
and TSO. ethtool can be used to disable both GSO and TSO.
Also, I can't see what firmware version you have on the NIC. Can you
verify that it's
Whoops, even if you hadn't updated the firmware, I gave you the wrong
link anyway.
I did see that the bug is fixed if you disable SG. I'm trying to isolate
the cause, and my colleague gave those suggestions. The goal is to fix
the bug, not leave you permanently without offloading capabilities.
Could you do two different tests?
1) Re-enable only Smart Connect. Does the issue persist?
2) With Smart Connect enabled, can you check if the intel-smartconnect
module is loaded? In your apport report, it looks like it gets loaded...
The kernel should output Disabling Intel Smart Connect if the
