I experienced similar symptoms while launching mozilla 1.7.12. I 
found that java was the culprit.

Here is a full dmesg captured by netconsole with the following 
scenario:
- boot to runlevel 1 (init 1)
- launch java (type "java[Enter]", no args).

The first oops is :
BUG: unable to handle kernel NULL pointer dereference at virtual address 00000034
 printing eip:
*pde = 00000000
Oops: 0002 [#1]
