What are your system spec's ?
I have a p4c800-e dlx Motherboard
atapi cdrom on /dev/scd0
lite on dvdrw LDW 4115 on /dev/hdc
HP psc 2210 on /dev/sda

The only 'failures' i get in /var/log/messages are:
hub.c: connect-debounce failed, port 2 disabled
sda : READ CAPACITY failed.
sda: test WP failed, assume Write Enabled

Yet I have the same problem as you, once every 5-10 times I
power down, the system hangs on 'unmounting file system'
I can't seem to get any errors on this after I reboot either.
Its a duel boot machine but I crash more often then I mount
a FAT partition. My /etc/fstab doesn't have any NFS either.

LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
LABEL=/home             /home                   ext3    defaults        1 2
none                    /proc                   proc    defaults        0 0
none                    /dev/shm                tmpfs   defaults        0 0
LABEL=/tmp              /tmp                    ext3    defaults        1 2
LABEL=/var              /var                    ext3    defaults        1 2
/dev/hdb7               swap                    swap    defaults        0 0
/dev/cdrom              /mnt/cdrom              udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu 0 0
/dev/cdrom1             /mnt/cdrom1             udf,iso9660 noauto,owner,kudzu,ro 0 0

See anything? I don't.
