I've received some reports about strange behavior of running GNU Radio
programs on Ubuntu 12.04, specifically when working with USRP signals.
Seems like programs are locking up. The same setup (version of GNU
Radio and UHD) apparently has no problems on 11.10, though.

There was a brief window where these symptoms occurred that was bisected down to this commit:

http://gnuradio.org/cgit/gnuradio.git/commit/?id=c78d307ecd5dac4e28190e5aa9b8377538f65ffa

It was reverted on master->next June 7.

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.
