[ewg] oops in today's daily build

[Woodruff, Robert J]

I am seeing an oops on today's daily build when
the pci driver has first loading the mthca driver
and it is in the process of initializing.
This is on EL4-U6 on X86_64.

The partial oops trace is below... the last of it scrolled off the
screen.
