@zavex this has to be related to my other thread here:
I think we are experiencing the same issue. If the wattage is high enough then the boot loop does not occur. Even if the wattage is low if the intensity value remains low too then the issue does not occur. With a neutral I have no issues. Without a neutral the dimmer falls into a reboot loop at higher percentages (and always if the intensity is set to full). I thought that it could be helped with some diode protection or isolation on the ground but that did not seem to help.
