No ethernet connection after reboot

Hi all,

I have a big issue with my sbrio 6905. When I make a reboot with it (hard or soft), the sbrio reboots, starts its startup application as usual but there is no more ethernet access at all. The 2 leds on the RJ45 connector are OFF and I'm unable to ping the card. The only solution is ton unplug the ethernet cable and plug it back or to switch the power off and back on

 

It is very annoying since I deployed several sbRIOs arround the world with 3G connections and I cannot reset them so I cannot make any software update since I cannot unplug the power.

 

Any idea?

I noticed that this seems to happen only when there is no Vbat on the card (ie no battery for saving RTC time)
