    That looks like the bug that was supposed to be fixed by commit
    44387e9ff25267c78a99229aca55ed750e9174c7, which is in 2.6.25-rc7 and
    later.

    What was the SHA1 ID of the head commit for the kernel source that
    gave you this oops? Did you have any other patches besides the one I
    sent you applied?

    Paul.
