Yes I do!
I will forward this to engineering RIGHT AWAY!

Subject: Re: [Karlnet] KN50 Problem with 8.x firmware
I've seen the same exact think on my first 3 KN-50 installs. I
replaced
the Dell cards all three times with older silvers and the links went
from marginally working to working perfectly.
Karlnet....you got your ears on?
