In case it's of interest or use, in tracking head daily for some time on
a Dell Precision M4400, I've seen similar symptoms.

But this morning, something happene dthat was rather worse than usual:
during "make installworld," (while I was otherwise occupied getting
ready to head in to work), the machine apparently rebooted.

Here are the last several builds I've done:

FreeBSD 11.0-CURRENT #1271  r267264M/267264:1100022: Mon Jun  9 07:47:43 PDT 2014     root_at_g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY  i386
FreeBSD 11.0-CURRENT #1272  r267321M/267323:1100022: Tue Jun 10 06:31:13 PDT 2014     root_at_g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY  i386
FreeBSD 11.0-CURRENT #1273  r267358M/267358:1100022: Wed Jun 11 08:51:08 PDT 2014     root_at_d130.dwolf.juniper.net.:/common/S4/obj/usr/src/sys/CANARY  i386
FreeBSD 11.0-CURRENT #1274  r267378M/267384:1100022: Thu Jun 12 12:51:53 PDT 2014     root_at_d130.dwolf.juniper.net.:/common/S4/obj/usr/src/sys/CANARY  i386
FreeBSD 11.0-CURRENT #1275  r267441M/267441:1100023: Fri Jun 13 06:34:57 PDT 2014     root_at_g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY  i386

Note that the reboot referenced above was while it was doiong the
installworld for FreeBSD 11.0-CURRENT #1275  r267441M/267441:1100023,
so it was running FreeBSD 11.0-CURRENT #1274  r267378M/267384:1100022
at the time.

And (to bring this back to the topic at hand), when I checked the logs,
the last thing I found before the start-up messages fro the reboot was:

[For completeness: after the machine came up, I re-started the "make
installworld", which then completed without further incident.]
