I found what may be the culprit in fstab.c where it would attempt to add to the list the "remounted" autofs mount, but as it was not already mounted (and in /etc/mntab ?) this added to the list the NULL values. This case is also common to mount, and a side effect of this seems to be the eleimination of some odd messages about failing to mount CIFS mounts in fstab (see bug #575293)
Using the package 'mount' (util-linux-2.17.2/mount) and the attached changes to fstab.c seems to work for me. ** Patch added: "Change to stop segfault in umount on non-existent remounts" https://bugs.launchpad.net/ubuntu/+source/sysvinit/+bug/579858/+attachment/1685468/+files/util-linux_2.17.2-0ubuntu2.debdiff -- umount segfault on shutdown when unmounting autofs mountpoint https://bugs.launchpad.net/bugs/579858 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
