Not receiving packets

I have a new install of snort, I have compiled daq and snort from sources.
I just used the default configure directives and received no errors.
When I run snort everything checks out and operates perfectly except
that it is not reading any packets from any of my interfaces, eth0 or eth1.
-T reports everything good.
I can capture packets using tcpdump no problem,
and in fact I can capture from either interface to a file and then run
snort with 'snort -r capture_file -c /etc/snort/snort.conf' and it works
and alerts as expected.
snort -i eth0 -c /etc/snort/snort.conf nothing
snort -i eth1 -c /etc/snort/snort.conf nothing
tcpdump -i eth0 -w capture_file works
tcpdump -i eth1 -w capture_file works
snort -r capture_file -c /etc/snort/snort.conf works
I have a test rule that alerts on all http traffic, so it is not hard to
get an alert.
Somehow I don't think DAQ is working properly, daq dump gives me nothing.
snort -i em2 --daq dump
