The command "umount -art afs" hangs, when inotify is compiled to the kernel (CONFIG_INOTIFY=y) My kernel version: gentoo sources 2.6.22-r2 When I recompiled my kernel without inotify (# CONFIG_INOTIFY is not set), the problem disappeared. Reproducible: Always Steps to Reproduce: umount -art afs Actual Results: I checked this command with strace. (strace umount -art afs) The last line was: sync( Expected Results: Do nothing, because I do not use afs! Actually I do not use afs, the script /etc/init.d/netmount, "generates" the following command: "umount -art afs,cifs,coda,davfs,fuse,gfs,ncpfs,nfs,nfs4,ocfs2,shfs,smbfs"

Please try w/ 2.13-r1
I was wrong in my first report. I had the kernel 2.6.19 (as the emerge info shows). With kernel 2.6.22-gentoo-r2 the problem disappears! I tried util-linux 2.13-r1, but with the kernel 2.6.19, umount still does not work.
Well, so upgrade your kernel.
