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. -- Mikolaj Golub
