This looks like what I have been observed within a recent -CURRENT
kernel, which indicates a bug that was fixed recently.

Would you please try the patch here:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/kern/kern_switch.c.diff?r1=1.111&r2=1.112

You can safely ignore failed patch of Hunk #1, but if Hunk #2 and/or #3
has been failed, please let us know your ident /sys/kern/kern_switch.c
output.

Cheers,
