Are you doing an "update list of packets in real time" capture?

If so, is network-layer name resolution turned on, or off?

If it's turned on, try turning it off - Ethereal might be blocking trying
to convert an IP address in one of the packets to a host name, if it's
trying to talk to a DNS server that's not responding (from the "futex" and
"eth0" references I assume you're using Linux, so this probably isn't a
NetBIOS name resolution problem).  It will *eventually* unblock, but that
could take a while.
