I observe /usr/lib/rtkit/rtkit-daemon using 30% of the CPU on Ubuntu 11.10 (Oneiric Ocelot). I tried to grab a stack trace with sudo gdb but this hangs up and I am unable to get the gdb command line back with <ctrl>C. See also repeating syslog output below. Issuing "sudo kill -9 1596" commands against the rtkit dawmon have has no visible impact.
