I have noticed a strange fault.. I get a reboot when trying 250-850-xlv-maemo21 and 250-900-xlv-maemo21 but it's stable at 250-810-xlv-maemo21 and 250-950-xlv-maemo21.

I would guess it has with the voltage settings but as i understand it.. the 810 is on low voltage, the 850 is on normal voltage and the 900 is on the same as 950 which is overvoltage. It is strange it works good on 950 but not 900 as they are on the same voltage.
