USRP2 dies

Hello,

My USRP2 dies during transmission when using interpolation rates less
than 24. When that happens, the USRP2 does not respond to any commands,
including find_usrps, until it is rebooted. Looking at previous threads
on this list, I noticed that other people experienced similar problems,
but it wasn’t apparent if they found solutions to them.

I have the USRP2 directly connected to a Dell laptop that has a Broadcom
NetXtreme BCM5755M chipset. I have enabled real-time scheduling in
limits.conf and the http://gnuradio.org/trac/wiki/USRP2GigEReports
indicates that my Ethernet chip is supported. What Ethernet
flow-control settings do I need to set in Ubuntu 9.04 on my laptop?

Thanks,
Ilya

Have you checked the flow control settings? What does ethtool report?
