Today I have upgraded the kernel in my VirtualBox (3.1.51.r27187) to the
latest current and have "em0: Watchdog timeout -- resetting" issue. My
previous kernel was for Mar 12.

Tracking the revision where the problem appeared I see that the issue is not
observed for r203834 and starts to observe after r205869.

Interestingly, if I enter ddb and then exit (sometimes I needed to do this
twice) the errors stop and network starts working.
