I have experienced this problem recently, too, after updating to 11.0-ALPHA3.  I get the watchdog timeout messages you give above when trying to buildworld with /usr/src and /usr/obj mounted via NFS.

My last successful build that did not have this problem is this one: FreeBSD beaglebone 11.0-ALPHA2 FreeBSD 11.0-ALPHA2 #0 r301779: Mon Jun 13 01:30:05 EDT 2016     pmather_at_beaglebone:/usr/obj/usr/src/sys/BEAGLEBONE-NO_WITNESS  arm

The build where this started happening for me is this one: FreeBSD 11.0-ALPHA3 #0 r301876: Wed Jun 15 14:23:28 EDT 2016

That's just two days apart.  Maybe that might help track down the potential revision that caused the problem.  I've not been able to buildworld via NFS since the problem began, so I've reverted back to the r301779 kernel for now.

Cheers,

Paul.
