If I followed the links correctly, that looks like r255507 on stable/9. The second part of that patch didn't apply cleanly to 9.2. I investigated and it looks like that is because r254442 had also been applied since 9.2. I'm guessing I should also apply r254442 as well (first)? I shall proceed with applying both patches, rebuild, and see what happens. --=20 John Marshall --LyciRD1jyfeSSjG0 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.21 (FreeBSD) iEYEARECAAYFAlJImcAACgkQw/tAaKKahKK2iwCgjmfyEGVXMzAtvUGRCiavPCXM cb4AoL8FtrgOzxyU85bDmWdjILWtIKuU =Gy4t -----END PGP SIGNATURE----- --LyciRD1jyfeSSjG0--
