 I guess you're suffering from difference issues. Support for Yukon
 Ultra was known to be unstable. I had tried hard to address the
 issue but lack of the hardware was major bottle-neck.
 
 Original submitter' hardware is not Yukon Ultra and looks like some
 timing issues related with interrupt level timer, Tx threshold. It
 would be great if original submitter can test previous patch.
