Shutdown Problem

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

Debian 6.0.6 (64 bit)/KDE 4.4.5

For some reason when I shutdown the system, either as a user or as root, 
the process hangs on:

Currently running process (pstree):

The only recourse I seem to have is to hit the reset button. 
Reinstalling psmisc did not solve the problem.

Assistance in solving this problem will be appreciated.

Thanks in advance.
