Hi,
One really simple way of getting some more info out of this is to take the EIP value (here c0181ca0) and run it through addr2line:
$ addr2line -e vmlinux -i c0181ca0
But you need to make sure that the bzImage/vmlinux you booted corresponds to the vmlinux you are running addr2line against.
This will tell you the source line which produced the page fault and will probably give a good clue as to what went wrong.
Thanks for reporting :-)
