Hi. I frequently get

  em0: watchdog timeout -- resetting

messages, followed by loss of network at the most inopportune moments.

It appears that it can be triggered by things like typing 'portinstall 
mozilla' over an SSH connection. But that is just a hunch.

Any ideas how to debug this further?

Hardware is a dell optiplex GX270. Kernel is -CURRENT from 29 june.

Cheers
Michiel
