What's happening is I think the same as what happens on the iMac: when
you run the BootX app to boot linux, and it asks macos to shut down,
macos shuts down the awacs, in such a fashion that the only thing that
will start it up again is a hard reset. :-( If you do
cat /proc/device-tree/pci/mac-io/davbus/awacs/compatible
and you see a string including "burgundy", that's the problem.
I have managed to work out quite a bit about the burgundy so far.
Its registers can be read as well as written, unlike the earlier
awacses, which makes it much easier to work out what macos is doing.
Shortly I expect to have a new dmasound.c which will support the
burgundy properly.
Paul.
