[linux-lvm] Unmounting file system hangs up...

[Thinking Outside the Well <rod rook gmail com>]

Hello,

I am using Fedora 10 and LVM. Lately when I shut down or restart the Linux box, it hangs at the stage of "Unmounting file system".

• Turning off swap  --- OK
• Turning off quotas --- OK
• Unmounting pipe file system  --- OK
• Unmounting file system ---  hangs up

Although I can turn off or restart the box manually, I am a bit concerned whether it is the beginning of more serious problems later. 
Your suggestion will be greatly appreciated.
