If I am reading the first log at <http://bugs.debian.org/607906> correctly, the
oops happened in the READ32 of

        /* Read doorbell and check for active bit */
        if (!(CHIPREG_READ32(&ioc->chip->Doorbell) & MPI_DOORBELL_ACTIVE))
                return -5;

But that's only from a quick look, and it doesn't make sense in light of your
later observations.

Would it be possible to sprinkle the code with printk calls to figure out
what's causing trouble (and for example where time is being spent in the
current version)?
