Try setting it to 0. It can be changed on-the-fly via `sysctl hw.em.rx_int_delay`. Look at the comments in if_em.c for an explanation. If that does not solve the problem, contact Intel support -- they have been very helpful to me in the past. > I'm experiencing a problem with the em driver in 5.1-CURRENT for my Intel 1000/Pro fiber Gbit adapter. > > The following is recorded in the syslog: > > Oct 15 18:17:49 shaolin kernel: em0: watchdog timeout -- resetting > Oct 15 18:30:25 shaolin kernel: em0: watchdog timeout -- resetting > Oct 15 18:30:27 shaolin kernel: em0: Link is Down
