Thanks Nicholas

I think those links refer mainly to getting as far as which released
ubuntu version exhibits the problem, I was intending (and have
achieved to some extent, as described in my other post) to build the
kernel and bisect it down to find the commit that introduced the
problem.  I was referring to
https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel for this.

Cheers
