Why are you focused on the interrupt rate anyway, do you hav= e some reason to tie it to the watchdog? You could turn AIM off (enable_aim) and see if that changed anything? It seems most the time problems show up they involve the use of lagg, if yo= u take it out of the mix does the problem go away?
