[ubuntu-uk] help needed testing upstream kernel

[alan c]

Can somebody please offer some off list support to guide me through
'testing using the upstream kernel'?
I found a bug re a particular webcam, which is being diagnosed, and I
have been asked if I can test using the upstream kernel. There are
some guidance notes, but I need help to get my head round it.
I am willing to try, but not having done anything similar I want to
avoid wasting lots of time or getting an invalid result.
Thanks
