Ok, for this to be helpful, strip out the "Jul 16....kernel: " bit, and
then you want to pass it through ksymoops, it's source is in
/usr/src/linux/scripts/ksymoops.cc (assuming your kernel source is in
/usr/src/linux), you can build it with "g++ -o ksymoops ksymoops.cc".

Now you need to tell it where the system map for that kernel is, and pipe
the oops through it, like this:

ksymoops /usr/src/linux/System.map <striped.oops.txt >decoded.oops.txt

You now need to post the oops, and the decoded oops ...

Hmm, it's not a good sign (not the oops as such, but the other stuff)
