[John Leake <jleake@xxxxxxxxxxx>]

Hi Chris, I have read the bisect info link and I am sorry to say it is
well beyond my capability.  For a start I have never built a kernel
before and have only ever used git clone in order to download and browse
through small source projects off-line.

Having said that it cannot be very time consuming for an experienced
developer to identify the problem when we know it is a module associated
with the touch pad and especially since the distance between the good
and bad versions is very close.

If bisected versions can be built for me and made available I will
gladly give them a spin and report my findings.
