Thats by design. There is an auto shutdown off at 4 hours of inactivity. 
  If you don't want that then change the powerd config file. in 
/etc/powerd set config_MAX_SLEEP_BEFORE_SHUTDOWN to "0" which will 
disable that feature.

Please upgrade to the latest powerd (powerd 28) and see if your issue 
persists.

http://dev.laptop.org/~pgf/rpms/olpc-powerd-28-1.fc11.i586.rpm

(you will need the --force option to rpm to install the package)
If it persists then please enable powerd tracing, recreate the problem, 
and then send the log file to pgf at laptop.org and copy me please.  You 
can enable powerd tracing by:

sudo powerd-config =trace-on

The trace log is in /var/log/powerd.trace

/var/log is a ram filesystem so if the machine shuts down you will lose 
the trace.  If you need it across a shutdown then edit /usr/sbin/powerd 
and change the  LOGFILE= to somewhere disk based.  Note: that the path 
to the logfile must exist.
