One question/problem - maybe an incomplete understanding of git. What I need to do is get to some version of 2.6.16 - as they all work for me. cut in my patches. And THEN start bisecting while retaining my patches. Is that going to work or am I going to have to repatch each time ? Basically can I use git to insert a patch into the middle of its delta history and then advance forward from there ? It is rapidly becoming obvious that competence with git could have big payback. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 dhlii at dlasys.net http://www.dlasys.net fax: 1.253.369.9244 Cell: 1.717.587.7774 Over 25 years' experience in platforms, languages, and technologies too numerous to list.
