Differences between mainline Marlin and Lulzbot Marlin?

Right now I’m having problems with LIN_ADVANCE, which is really my biggest reason for switching. Setting the advance K causes bad things to happen, i.e. the extruder makes a noise for a half second and then the entire printer becomes nonresponsive. From searching around, it seems like LIN_ADVANCE in combination with some other features puts a lot of strain on the poor ATMega2560. I’m going to try turning down microstepping to 1/8, and see where that gets me.

Please read my last post here, there was a bad bug in two ISRs that might be related to that. If you still have problems, please post the gcode snipplet where the problem happens and I will try to find out whats going on.
