The system was a freshly installed 64-bit Ubuntu 12.04 with Boost 1.46.1, using the build-gnuradio script for compile and install on June 6. After the revert the issue went away entirely. That original commit looks entirely correct, so I suspect there is a Boost problem with mutexes in 1.46. I can't say whether or not this is the cause of the issue you're hearing about. If so, a current master build with proper and verified cleansing of the old UHD/GNU Radio libraries should make the symptoms go away. Johnathan
