Imho it would be much nicer for tracking down problems, if people just continue their graph, without doing rebase. Stephen, as you've more experience with the other maintainers: Would it not be possible to retrieve a branch from most subsystems that is never rebased? Imho doing rebase breaks alot of possibilities with git, as you remove commits and break the history (which is what makes git powerful for me). > > - And would a non-rebased tree not make life much easier for debugging > > purposes? > > I don't know. What it would do is produce a lot more merge conflicts as > patches are moved around, changed, removed etc on a daily basis. The only issue I see is with rewritten patches. Otherwise git-merge should detect already applied patches and without git I see git-format-patch and git-am as quite strong tools. I must confess, that I _really_ like the idea of doing git-fetch && git-merge linux-next, so git-bisect works for all versions. > > My motivation is to find out the reason why xorg crashes now together > > with the xorg guys.

Just compiling..the dual core 1.83ghz cpu is just too slow...reboot... works. I'm writing this E-Mail running 2.6.27-rc1-denkbrett-00156-g94ad374 under xorg.
