[Discuss-gnuradio] problems installing UHD on USRPE100

[Achilleas Anastasopoulos]

I have followed the instruction for installing UHD from source to USRP 
E100.
I have also installed the latest images (as of 1/22/2011).

the benchmark_rx_rate command gives me the following (see attachement at 
the end of the email.)

I am worried about the warning and also about all the errors i get.

ANy help will be greatly appreciated.

Thanks
Achilleas
