Hey, after experiencing some problems (time outs, etc) with the current UHD develop version (master branch) I changed the UHD version to 3.10.2 (maint branch, #122bfae).
To do so, I just used the prefix recipe gnuradio-stable via pybombs. Now I'm not able to transmit even low bandwidth signals. My setup is - X300 via 1G ethernet - gnuradio (maint branch) - Debian with kernel 4.9. I used a simple flow graph with just a sine source directly connected to the USRP sink block. Even for sample rates below 2MSamples/s one of the cpu core of my Xeon E5-2630 v2 is 100% busy. Observing the cpu load with htop, I recognized that most of the cpu load is red which indicates kernel space activities... After several seconds I finally got many "U"s in the console window. Some ideas how to isolate the problem? Thanks in advance!
