I went to one of the archives of the linux-kernel mailing list
(http://www.uwsg.indiana.edu/hypermail/linux/kernel/index.html is searchable).  A
search on "unable to handle kernel null pointer" returned a number of
matches.....

You appear to be lucky that this is only happening to you during shutdown.  Most
of the other posters are seeing this with several apps up and running, as appears
to be a problem with virtual memory.

How is this box configured?  Do you have an unusually large amount of RAM?  swap
partitions? On-board cache?  One post indicated that their problem was fixed by
disabling the cache (in BIOS setup?)  Another post described a kernel compiled
for huge amounts of RAM being run on a different machine.....
