I did an 'apt-get dist-upgrade' and there was a kernel upgrade, so I rebooted. When the system came back there was no functional networking. Everything looked fine, I couldn't reach anything besides loopback.
On a hunch, I commented out br0 interface from /etc/network/interfaces and bounced networking (/etc/init.d/network restart) and all OK.
Then for grins I added br0 interface back and bounced networking again and, huh, all now seemed OK.
So I tried rebooted and all was still OK.
Chalking it up to a mystery for now unless problem returns.
