That sounds extremely like an 8390 boog rather than just a vendor specific sort
of thing.  There's a publishing opportunity for anyone willing to do a 
short novel on "NS8390 Bugs.                           |  NovAtel Commnications Ltd.                               | <nothing I say matters anyway>
