(I think there are some characters missing in the above log,
particularly the page numbers.)

However, the driver apparently works on the same system in a !SMP kernel
configuration.

The complete report can be found at <http://bugs.debian.org/647900>.
Can you suggest any way to correct or debug this problem?

Ben.
