[SOLVED] Lockup on halt after Unmounting Filesystems message

For the a while now whenever I halt the machine, it locks up on "Unmounting Filesystems . . ." before it gets to the "[OK]" message. Do I need to fsck the disk or something? or is it the ntfs mounts maybe? I'm unsure of how to troubleshoot this.

Try unmounting different mounts before shutting down and seeing if it hangs up.

Like, first, try unmounting everything nonessential first and see if it works. Then start over and leave mounted different mounts or types of mounts until it stops working. You can narrow it down this way.

BradN, that helped me find the issue. The root problem was that I didn't have ntfsmount in my default runlevel.

My mpd is dependant upon an nfs mount for the music directory. I think it was hanging trying to umount that nfs dir before mpd shutdown. Once I put ntfsmount into default it was able to order the shutdown correctly (since mpd has nfsmount as one of its dependencies). I thought I had ntfsmount in there already but I guess not.

I found the problem when manually unmounting stuff and it wouldn't umount the music folder then it dawned on me. Thanks BradN!

No problem!

I know how frustrating those sorts of things can be, especially if updates to init scripts change dependencies between "use" and "need", etc...

My personal gripe: Why does sshd "need" networking? Loopback is enough to run it, and if I switch it to "use", it plays nicer when I manually set up a connection, as in... it's actually running when something crashes horribly and I need to remote in! But then I mindlessly update the init script next time sshd gets installed and start all over.
