I see this regularly in the Jenkins results:
https://jenkins.freebsd.org/job/FreeBSD_HEAD-tests/1108/console

WARNING pid 60945 (fifo_misc): ioctl sign-extension ioctl ffffffff8004667d

Need to figure out where what the root cause is for this warning.

Thanks Craig for the fix!
Comment 4 Enji Cooper freebsd_committer freebsd_triage 2015-10-24 23:30:45 UTC 
Closing bug because the issue was relatively benign, so fixing on stable/9 isn't needed.
