[Voyage-linux] Problem creating database on alix

Intermittent problem with the Alix was found, the cpu was not well soldered
to the board, infact, flexing it a little showes that the cpu looses
contact and the o.s. crashes. I've tried to reflow it in a oven but got a
totally non working board and melted connectors (even if checking the temp
i've not got it over 220°C), so, did you sell only alix 3D2 alone? If yes
at how much (I'm in Italy)? Database creation still to be investigated.
Thank you, best regards.
