Hello! With '/dev/ad0s1 /mnt/ad0s1 ntfs ro,noauto 0 0' in fstab, if I issue 'mount /mnt/ad0s1' twice, I always get a panic with the message: panic: lockmgr: locking against myself If I issue 'mount_ntfs /dev/ad0s1 /mnt/ad0s1' twice, there is no panic. I only get 'mount_ntfs: /dev/ad0s1: Operation not permitted' as expected. For a different (non-ntfs) filesystem, using plain mount twice gives 'Operation not permitted', too. System is: FreeBSD janh.freebsd 6.2-RELEASE-p4 FreeBSD 6.2-RELEASE-p4 #0: Thu Apr 26 17:55:55 UTC 2007 root@i386-builder.daemonology.net:/usr/obj/usr/src/sys/SMP i386 Can anyone reproduce this? Just for my curiosity: What is mount doing differently than mount_ntfs? Thanks, Jan Henrik
