For no reason one of my MD's did not shutdown when powering it of from the power menu. No display anymore but the system still runs... a bit, ie powerlight is on but no interaction with lan, keyboard or monitor. Holding the on/off button for some time does the job.
About 2 days ago I noticed that shortly before the display disappears I saw the word "suspend". So I performed a shutdown from the CLI and even a reboot. All working ok but it looks like the md shutoff button in the power menu brings it into suspend in stead of shutting down the whole MD.
When booting I always get the question "reload router?" as per http://forum.linuxmce.org/index.php?topic=8910.0
No clue how to get it out of suspend modus. Maybe somebody can shed some light?
edit: saw the following in the updates list:
Update 2010-08-02 23227
pluto-app-server (145,126) - Do proper check to determine if suspend is supported
Could there be any relation?
