2.6.32.1: BUG and panic: unable to handle kernel NULL pointer dereference at 000000000000001f

Hi,
we tried to upgrade a couple of our proliant servers from 2.6.31.6 to
2.6.32.1.
On two of our DL385g1 servers we had problems booting 2.6.32.1, as they
paniced.
One of them eventually booted correctly when it was decided to log its
serial console output; that strategy proved unsuccessful with the second
box.

hosts the complete serial console output.
What I caught on the second box, that eventually decided to boot is
similar, but not identical:
