Hi Eduard,
I have just filed a bug on the ubuntu bugs forum at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1495043 .
Essentially the problem is that the driver prevents my XPS15 from resuming from suspend.  As a temporary solution, I have created a script for systemd-sleep that unloads the wl driver prior to suspend, and reloads it after resuming.  This fixes the problem, but is really just a hack.  You can see my script on the bug report.

I just wanted to let you know about this issue as the maintainer of the
package.

Thanks for all of your hard work in providing this software.

Thanks and Best Regards,
Mark Pointing.

Title:
  Suspend/Resume Regression 3.19.0-28-generic Dell xps15

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Suspend resume was working on 3.19.0-26 but 3.19.0-28 appears to
  suspend, but no longer resumes.  Relevant portion of dmesg info using
  pm-trace is as follows:

  [    1.400305] Write protecting the kernel read-only data: 12288k

  To reproduce the bug:
  1) Boot into Ubuntu Gnome with kernel 3.19.0.28-generic
  2) Log in to desktop.
  3) Close laptop lid
  4) Wait about 10 seconds (doesn't seem to be critical how long you wait)
  5) Open laptop lid.

  What happens:
  The keyboard backlight and the power button light come on, but the screen remains blank.  Using Ctr-Alt-F1 does nothing (can't get to a virtual console, indicating that it's not just X that has stopped)

  What I expect to happen:
  On opening of the laptop lid, I expect the lockscreen to show.

  Other info:
  This laptop has nvidia graphics disabled using nvidia-prime
