A long shot at this, but were all the pf_ring modules (driver, kernel, pfring libpcap, pfring daq) compiled and installed from the recent source? If you revert back to the stable version (apt/yum install), does it work? You can also try uninstalling then make clean and make distclean, and recompile again.

Topic says it.  Config test run:

sudo snort --daq-dir=/usr/local/lib/daq --daq pfring  -T -c
/opt/snort/etc/snort.conf

backtrace:

sudo snort --daq-dir=/usr/local/lib/daq --daq-list
Available DAQ modules:
pfring(v1): live inline multi unpriv
pcap(v3): readback live multi unpriv
ipfw(v3): live inline multi unpriv
dump(v3): readback live inline multi unpriv
afpacket(v5): live inline multi unpriv

Not sure of my next step.
