Found a thread suggesting IPv6 as one possible cause of this sort of
behavior, so I disabled it (/etc/sysctl.conf, I think) and got rid of
the IPv6 messages in the log. That made it clear that DHCP was timing
out, so I just set a static address, and the problem is solved for me.
(I prefer not to use DHCP, anyway.)
