machine crashes on suspend

[Jeff Abrahamson]

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.
