Natty kernel oops 3/6 build iso AMD64 on x120e

[Manoj Iyer]

I was trying to install an X120e with Natty AMD64 USB image (created
with no persistent storage) 3/6 build iso, and I got a kernel oops in
__mark_inode_dirty(), I traced it down to a NULL pointer dereference,
and looks like someone has already posted a patch to LKML, I was not
able to recreate this oops with i386 kernel.
