hm.
- Try to get the full oops record,
BUG: unable to handle kernel paging request at virtual address 01020304

find out what the faulting address is
("unable to handle kernel paging request at virtual address xxxx") and
see if that lines up with any symbol in .vmlinux.
Did you mean "list 01020304"?
- Might be something bad in numa_policy_init(). I assume you don't have
CONFIG_NUMA=y ;)
No, I don't.
This'll be hard to diagnose without a full oops trace.
