Jul 29 09:11:58 gk-intern kernel: em4: Watchdog timeout -- resetting
Jul 29 09:11:58 gk-intern kernel: wan0: link state changed to DOWN

There are other em interfaces in this box, but they do not have
the timeout problem:
dev.em.0.%desc: Intel(R) PRO/1000 Network Connection 7.2.3
dev.em.1.%desc: Intel(R) PRO/1000 Network Connection 7.2.3
dev.em.2.%desc: Intel(R) PRO/1000 Network Connection 7.2.3
dev.em.3.%desc: Intel(R) PRO/1000 Network Connection 7.2.3
dev.em.4.%desc: Intel(R) PRO/1000 Legacy Network Connection 1.0.3
dev.em.5.%desc: Intel(R) PRO/1000 Legacy Network Connection 1.0.3
Why are em4 and 5 using the Legacy ?
>How-To-Repeat:
