Do you have a scope available to you?  Is it showing about the same
waveforms as your previous working version?  Try looking for
subharmonic operation... layout changes can cause this for no obvious
reason sometimes.  Also, are you *sure* your inductor really is what
you think it is?  Do you have a means to measure its value, or to
observe the waveform of the current passing through it?
