On my n800, I enabled the soft poweroff in systemui.xml... but every time when I put the tablet in soft power off, the d-pad led is blinking. In control panel->display->led all the check boxes are unchecked. Does anyone else have this problem?

I don't have new emails (I don't use the email app on the tablet), I don't use any kind of alarm on the tablet. I reflashed yesterday and installed the two OS updates, so this is a clean tablet.

Any ideas?
