Sigh... one more try, one more failure...

This time I tried to use git-bisect(1) to see if I couldn't track the
change more easily.

So, here's what I did:

    $ cat ./bisect.sh
    #! /bin/sh
    
    if ! git grep -q -e blacklist_iommu -- drivers/pci/intel-iommu.c
    then
    	exit 1
    fi

    $ git bisect start v2.6.28 v2.6.27 -- drivers/pci
    Bisecting: 70 revisions left to test after this (roughly 6 steps)
    [a0bfb673dca8a2b4324fe11e678ec6d6a9ad67e0] Merge branch 'linux-next' of
    git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6

    $ git bisect run ./bisect.sh 
    running /dev/shm/bisect.sh
    Bisecting: 42 revisions left to test after this (roughly 5 steps)

Do you know what's going wrong ?

Thanks
