https://bugzilla.kernel.org/show_bug.cgi?id=218789 --- 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. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
