>Description:
I recently tried to suspend my new laptop for the first time.  Rather
than suspend, the screen turned off, flashed, there were a couple of clicks (from the hard drive and DVDROM, I believe), then it silently rebooted.  If there were any console messages, they were hidden by the turned-off screen and didn't survive the reset.

I have a verbose boot as well as ACPI info; if there's anything I can do further to try to diagnose this thing, please let me know.

>How-To-Repeat:
'apm -z' or 'zzz' on an Inspiron 5160.
