I saw a fix go into msdosfs_vnops.c recently, which is presumed to have fixed this panic: panic: vrele: negative ref cnt However, I seem to remember that you're using 3.4-RELEASE. The fix has only been applied to the development branch and to RELENG_4. You can try to come up with a patch for yourself based on: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/msdosfs/msdosfs_vnops.c.diff?r1=1.95&r2=1.95.2.1 Ciao, Sheldon.
