Ok, I have built an image for each of my commits, and I have attempted to rebase my changes
so that these kernels should work on un-patched drivers.  I have not actually tested these
various images on un-patched drivers, so if you see any un-expected problems, let me know
and I can test those specific images.

From your previous testing, you know the first commit should be OK for DFS, and the
last commit (172) is not.  To bisect, choose an image in the middle (ie, commit 86)
and see if it works.  If so, choose middle one between 86 and 172, if not, choose middle one
between 0 and 86...repeat until you find the first bad commit and let me know what that
is and I will try to figure out the problem in the firmware.
