[Mark Pointing <1495043@xxxxxxxxxxxxxxxxxx>]

Further information, it turns out that pm-suspend is no longer used, and
systemd-sleep is the new system.  The scripts section of pm-suspend is
still there, but it is broken as per
https://launchpad.net/ubuntu/+source/pm-utils/+bug/1455097  (why does
everything I look into seem to be broken????).

To fix the problem, I created the script (make it executable)
/lib/systemd/system-sleep/broadcom_wl_suspend

with the contents
[code]
#! /bin/sh
#mp035: unload buggy broadcom sta driver during suspend.

case $1 in
     pre)
	modprobe -r wl
        ;;
     post)
	modprobe wl
        ;;
esac
[/code]

This has fixed the problem.  I'm not sure where to push this from here,
either the 1) the broadcom package should add ths script, or 2) or the
broadcom sta driver needs fixing.  Perhaps (1) immediately while we are
waiting for broadcom to fix (2)?

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:

  [    1.168740] registered taskstats version 1

  [    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
