Yes there were substantial changes to the init order and legacy support related things. While the changes themselves should all be for the better it's always like fix it for some, brake it for others. What revision are you seeing this with? A syslog would be most helpful of course. Probably best if you'd open a ticket for that and attach all the info you can gather there. Regards Michael
