I have few Desktop and laptops that gets bsod acpi_bios_error in MS windows with the cause of "using area of menory already reversed to the system".  Its due to this line in Device (BOX3) "OperationRegion (OPRG, SystemMemory, ASLS, 0x2000)" in the https://review.coreboot.org/c/coreboot/+/27711/7/src/drivers/intel/gma/acpi/... file.  If I remove the OperationRegion line MS windows boots, can anyone explain what this line is doing or a fix? thanks
