Acrn-dm actually uses 'iasl' compiler from the Service OS (by default, the one in /usr/sbin)[1], could it be that it's the version of that tool that is causing trouble? The one shipped in Clear Linux these days is version 20190215. What is the version you have in your SOS?

The commit mentioned in that commit is, sadly, in the 0.7 release.

This is very similar to an issue we hit a little while ago related
to ACPI (and

IASL):

Hi,

My setup with an X SOS and Weston UOS works fine with 0.6, but
upgrading to 0.7 it fails:

I filed this as

thought I'd try the list too in case anyone not watching the issues
has any good ideas.
