[Joakim Tjernlund]

Two times I have gotten this OOPS at boot:

argh. node added in wrong place
Unable to handle kernel paging request for data at address 0xffffffee
Faulting instruction address: 0xc00d5244
Oops: Kernel access of bad area, sig: 11 [#1]

I can't reproduce it, but I figured I should report it.
