If ringing is inevitable why not add some additional
capacitance (as is done in TV flyback circuits) to
make the ringing period something like 2X the gate
drive frequency. This will be a "tuned" flyback but
at least you could put the "ringing" in a place where its
useful. This should stop the squiggles since you will turn
the FET on at precisely the correct time that the squiggle
tries to go postive for the 1st time.
