Thanks Daniel; I'm happy to collect local information/debug etc, sure. Alas, it looks like that repo is in an unexpected state: $ git clone git://people.freedesktop.org/~danvet/drm Cloning into 'drm'... remote: Counting objects: 2631581, done. remote: Compressing objects: 100% (395986/395986), done. remote: Total 2631581 (delta 2211094), reused 2630318 (delta 2209899) Receiving objects: 100% (2631581/2631581), 615.36 MiB | 1.77 MiB/s, done.
