Is this still happening in the latest Linus tree?

If so, please send some more oops traces so we can see if it's always happening
in the same place.

Please only send the first oops trace after a bootup: the one with [#1] in
the "Oops:" line.  All the others could be a consequence of the first.

Thanks.
