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.
