I updated from a gnuradio 3.7.3 git version (before 3.7.3 was officially released). I updated the pybombs recipes via git before the update. "Pybombs update" removed all updateable gnuradio stuff and installed it new as expected. I can actually confirm the problem now on two machines. Both running XUbuntu 12.04 64bit. One with an Intel core 2 due and the other with an AMD "APU" processor. I usually had no problems running gnuradio, gqrx and other related applications on both machines. Can you explain what that rtlsdr_read_async... message means ?
