	I looked at your fstab and it is VERY BAD! You have not done it as it 
should be. Here is mine for comparison:

karl at Jaunty:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# / was on /dev/sda9 during installation
UUID=b90a944a-81b4-417d-b481-3f3daf3af809 /               ext3 
relatime,errors=remount-ro 0       1
# swap was on /dev/sda3 during installation
UUID=77cb374a-6349-427e-9b57-ea6776f4a52d none            swap    sw 
           0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0
# /dev/sda5       /home       ext3     defaults        1   2
UUID=40cb6175-3c6e-4a7f-ae57-083cccbbba63 /home  ext3 defaults 1  2

So fix up yours and see if the kernal panic goes away.
