Well kmalloc is failing. It should not be though, even if the
current node is offline, it should be able to fall back to other
nodes. Stephen's trace indicates the same thing.

Could you try the following patch please, and capture the output
it generates?

With this patch i don't get any extra information other that what is already reported.
Have attached the boot log captured using loglevel=8 mminit_loglevel=4 options.

Thanks
