This is the first time I've decoded an oops, and since I had to decode it on a different kernel (2.5.25) than the one I'm debugging (2.5.50 + Dec 6 ACPI patch), and I couldn't get the ksyms file, I used -K ... and because I built w/o modules I used -L and -O.  Let me know if I did it wrong or if you need more info...  Thanks.  (Also I had to transcribe the oops by hand ... I'm pretty sure I got all the values right but I could have missed something)

ksymoops 2.4.4 on i586 2.5.25.  Options used
     -v vmlinux (specified)
     -K (specified)
     -L (specified)
     -O (specified)
     -m System.map (specified)
