[App_rpt-users] URI and URIx Testing

[David McGough]

The problems with this motherboard are due to lack of support for their
recent chipsets in the old Linux kernels found in CentOS 5. Upgrading the
kernel will resolve the problem. Those boards have very nice features, 
I've got a couple similar ones deployed and they've been completely 
stable. As I recall, I'm running a "hand cooked" 2.6.32 kernel.
