If this kernel is not going to hit -updates shortly (i.e. days), can
something be done to pull or downgrade the broken kernel? At least
revert linux-image-generic to depend back on linux-
image-4.4.0-57-generic which doesn't have the issues and will stop more
people from upgrading to a broken kerne
Looks like it is not working today with any of the above kernels - I had
multiple screens working ok on Friday with the mainline kernel, but
today it is not working. I'm not sure what changed, I will attach the
dpkg log, but am going to have to go to windows as this is a work laptop
and i can't spe

Worth testing if you also have this problem. Also check your BIOS versio
I've just updated the dell bios to 1.5.3 and the crash still occurs. I
noticed that plugging into a 4k tv via the builtin mini display port
also causes the crash, though not always.

It is not possible to test this on the latest development image as the
nouveau driver does not resume (desktop completely locks up), and the
e1000e problem is intermittent, so a full reboot between tests is
infeasible.
Is there any debug info that I can gather to assist here? Any logs or
trace?
*
For reference I tried booting the latest mainline kernel, and apart from
screwing up unity (see bug 1215828) it suspended once, then failed to resume.
There was a reason I started using the nvidia driver, and that is because the
nouveau one fails to resume. So testing on that won't be possible.
Hi, I updated to the new bios but still had the problem earlier today.
