What was the reasoning behind this change? Linus gave more details somewhere earlier in this thread, before it veered seriously off-topic. Short version: console shutdown was being done incorrectly, and in a way that prevented STR from working on Linus' x86-Apple. He was using netconsole. Likely a better fix is available (e.g. suspending console device and its ancestors at the latest possible point), but nobody has yet made the time to produce one. - Dave
