Public bug reported:
On a Dell Precision M3800, suspend has begun leading to crash.
Suspend happens by running /usr/sbin/pm-suspend
On resume (either by opening the lid if it was shut else by touching the
power button), the fan comes on and the power button lights, but the
screen does not activate. On reboot, kern.log shows no events from
suspend until reboot.
This used to work correctly most of the time. Occasionally and rarely,
it still works.
