Unfoutnately I don't have any em(4) devices but I think the first step
to diagnose
this would be to enable debugging output for the em driver.

Hi Jan/John/Adam,
I had the em watchdog timeout problem also today on a newly installed
6.0 GENERIC.MP, though luckily it was transitory.
Example error message: "em1: watchdog: head 133 tail 132 TD 133 TDT 133"
As soon as it happened, the network connection would suffer of severe
hickups - at least some seconds of traffic interruption.
It seems that it was correlated with ISP hickups as it happened ~10
times across ~3 reboots during ~1 hour only, and during the same period
getting any DHCP or PING through was difficult to impossible (also after
fresh poweron and boot), and TCP would not connect, or disconnect after
connect, or act otherwise strangely, and the modem's LINE LED was red a
lot of the time.
If I would experience it again, I would switch the em driver into debug
mode and report back here.
