Well - that made it hang hard.

I’m between gigs right now, taking time off, so have some cycles to work on this.  I’d love to dig into myself, but would need some guidance.  I can also probably give you remote access to this particular box as well.

I’m assuming there is one particular device that is throwing off the ACPI code - is it possible to black lists those address temporary ?   It’s not clear to me what hardware it is stumbling over.

Thanks !
