5.2.1-RC2: Fatal trap 12 when ACPI enabled

Hi,

When I boot 5.2.1-RC2 on a ASUS A7Nv8 Deluxe OEM Board (the "OEM" 
meaning it's a A7N8X standard with the Deluxe's MCP-T  
Southbridge) with ACPI enabled I get a "Fatal trap 12".  It 
disappears when I boot without ACPI.

Below are the last lines appearing on the console.

regards,
Robert
