Hi Christian, happy new year and I hope you had a few restful deays off. I've pushed a new tree to: git://git.infradead.org/users/hch/misc.git powerpc-dma.6 Gitweb: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/powerpc-dma.6 Which has been rebased to the latests Linus tree, which has a lot of changes, and has also changed the patch split a bit to aid bisection. I think http://git.infradead.org/users/hch/misc.git/commitdiff/c446404b041130fbd9d1772d184f24715cf2362f might be a good commit to re-start testing, then bisecting up to the last commit using git bisect.
