I recently updated my server to the latest 8-STABLE, and upgraded to v28 ZFS. I have not had these problems on any other version of 8-STABLE or 7-STABLE, which this box was upgraded from some time ago.
Now, during my weekly scrub, I get the following messages and em0 is unresponsive: Jun 12 03:07:58 foghornleghorn kernel: em0: Watchdog timeout -- resetting Jun 12 03:07:58 foghornleghorn kernel: em0: link state changed to DOWN Jun 12 03:08:01 foghornleghorn kernel: em0: link state changed to UP Jun 12 03:08:47 foghornleghorn kernel: em0: Watchdog timeout -- resetting Jun 12 03:08:47 foghornleghorn kernel: em0: link state changed to DOWN Jun 12 03:08:50 foghornleghorn kernel: em0: link state changed to UP My scrub is scheduled to start at 03:00:00, so it looks like watchdog timeouts start occurring pretty quickly once I/O ramps up. Here's some possibly relevant information, let me know if anything else would be helpful to troubleshoot.
