[lug] RHEL6 USB and network issue

Thanks for the info Maxwell!  It's definitely pointed me in the right 
direction.  I could find no option to turn off the 3x power for the usb 
in the bios and upon further reading, for the 3x to work, you are 
supposed to load up a specific driver. I'm going to assume that feature 
is turned off for now.  But I did find this link:

http://ubuntuforums.org/archive/index.php/t-2111223.html

And it seems that if you set  IOMMU to ENABLED in the bios the problems 
disappear using Ubuntu.  They even mention the board I have so I'm 
hopeful but when working with RHEL I've found that a little skepticism 
is warranted.

I'm trying this now but need to head out soon so I'll let the install 
run and test it tomorrow morning.  A 12 hour work day is long enough for me.

Thanks for the help and I'll be sure to post my progress in case anyone 
else runs into this similar issue.

cheers

Steve
