Developers confirmed that nullfs was the neccesary ingredient required to induce this panic. A fix was produced, tested, and committed to head on 2013-10-10 as r256211. I applied that patch to releng/9.2 a week ago and have had releng/9.2 + r256211 patch running on two servers since then. All looks good. That patch was MFC'd to stable/9 this morning as r256590. Thank you to those who diagnosed this panic and produced the patch. --=20 John Marshall --St7VIuEGZ6dlpu13 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.21 (FreeBSD) iEYEARECAAYFAlJfgAgACgkQw/tAaKKahKJU/ACfdj3IgjstiJ8g1E3lv7Wv6nM0 ayEAn0x8A39SFUrauspKQi2iRH+vicN2 =pDrV -----END PGP SIGNATURE----- --St7VIuEGZ6dlpu13--
