I'm trying to get an IBM RS/6000 43p/240 booting into linux, I'm having a bit more success that I've had previously, at least this time round when i specify video=ofonly or video=keep the booting process gets past the "building of device tree..." part and goes on to say "booting..." but then it hangs there. Has there been any progress on these machines? Does anyone have some suggestions that I could try? Thanks - David
