Now I'm getting uncommanded shutdowns again.  I did file a bug report.
 There are very similar bugs but usually associated with hang ups and
failures to suspend or hibernate.

My system seems to be hibernating great--except I don't want it to!

The message I see on the console after an uncommanded shutdown is:

[ 5904.836193] Power down.
[ 6280.181570] System halted.

I see messages about hibernate in /var/log messages but I can't see
what triggers it.  From searching around, it looks like lots of
programs, some apparently conflicting, can affect hibernation.

I am real confused and would appreciate any more
suggestions--especially about debugging instrumentation to see what is
