You have encountered the GNU Radio 3.0.3 bug with Linux kernel 2.6.20. There is already a fix available, but it hasn't made into a new GNU Radio release. Please obtain the Subversion client software (install with Synaptic in Ubuntu), then follow the directions for checking out and installing GNU Radio at: http://gnuradio.org/trac/wiki/BuildGuide Be sure to use the latest release 3.0 branch code at: http://gnuradio.org/svn/gnuradio/branches/releases/3.0 > *Querry B :*How do I get usrp_fpga.rbf and usrp_firmware.ihx, if they > are needed?
