[21:31] <phillw> Hi good people, I'm testing yakkety and seem to have acquired a kernel not in the usual numbering system.... 4.4.0-9134-generic I was expecting some more along the lines of 4.4.0-35-generic etc. 
[21:31] <phillw> 1) Would I be best placed to remove this one so that the numbering sequence reverts and 2) how did this occur?
