What do these isp messages mean?

It seems em0 went down the same time.
The serial console was fine, and em1 was fine too.
But I had to reboot to get em0 working again.

This is on ia64 r221340

After reboot:

ZEEV> ifconfig -a
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
