I'm getting a lot of "acpi_spmc0: Unknown revision" messages from this
driver on my box, below is the full (non-verbose) boot log. However
the affect of those messages is not clear to me. Does it mean S0ix
won't work? Or are those just warning messages?
The logged text and occurrence of those should be adjusted, it's too
verbose right now and the printed message doesn't help the user figure
out what's going on.
Thanks, Roger.
