--- Comment #7 from Heikki Krogerus (heikki.krogerus@xxxxxxxxxxxxxxx) ---
Thanks! I can see that "ECSI" EmbeddedControl OpRegion inside the scope of the
UCSI device in your tables, which should be fine.

I don't think we have a global handler for the EC OpRegion in Linux, which I'm
quite certain we really should have - just like we have for the other types:
SystemMemory, SystemIO, PCI_Config, etc.

This may actually be a missing feature in ACPICA, so other operating systems
may also be affected.

I'll see if I can get the ACPI/ACPICA guys to take a look at this.
