[Buildroot] Auto standby after 10 minutes, what origin?

[Damien Borie]

Hello,

I made a distribution for a PDX 089T with a Vortex CPU. Everything works 
fine, but, after 10 minutes, I always have an automatic standby. It 
comes with Xorg started and also in console without any X server.
So I conclude it isn't a Xorg configuration problem.
But, where does this standby could come from? Kernel configuration? 
Hardware?
I thought somebody here might have already encountered the problem...

Thanks.
