Re: (ASCEND) Bad Flash rom ?

    Thats what I assumed also! My unit boots just fine, works great, until your
introduce ethernet traffic (alot of it). It seems to slow wayyyy down even in
the console then eventually (every 60 seconds or so) resets itself.
    I figured if its a bad flash rom it wouldn't do diddly! Or wouldn't take new
code anyway. I just upgraded to 6.0 (serially this time) just to see... same
deal, real slow!
