            Bug ID: 206567
           Summary: [msk] msk0: watchdog timeout - 88E8053 on i386
           Product: Base System
           Version: 9.3-STABLE
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: bugs.freebsd.org at cmb.ch

On my MacMini (Late 2006, Macmini1,1, MA607*/A), the msk0 interface shows
usually this:
Jan  1 22:29:17 beastli kernel: msk0: watchdog timeout
Jan  1 22:29:17 beastli kernel: msk0: link state changed to DOWN
Jan  1 22:29:20 beastli kernel: msk0: link state changed to UP

and thereafter the interface won't transport any data anymore. Only a reboot
helps. This is since 9.2 (for over a year).
I have looked at patches found in this bug forum but it didn't help.

This happens when quite some traffic goes oer the interface, I presume. It
happens either once a week or every 30 minutes...

Anything I can switch on/off to configure?
Or anything I can do to circumvent the reboot? (as kernel module could be a
way) as read in #150257 ?

Thanks
Christian
