I assume that this warning isn't causing any severe issues as it seems to be pretty common throughout the DSDT on my supermicro: acpi.dsl 3213: Acquire (W627, 0x1388) Warning 1103 - Possible operator timeout is ignored ^ However the last few look very interesting and most probably are related to why my machine kind of dead locks when a PCI card is in the PCI-X slot: acpi.dsl 4044: Field (IDE1, DWordAcc, NoLock, Preserve) Error 4026 - ^ Access width is greater than region size acpi.dsl 4046: MAP, 8, Error 4027 - ^ Access width of Field Unit extends beyond region limit acpi.dsl 4048: PCS, 8 Error 4027 - ^ Access width of Field Unit extends beyond region limit acpi.dsl 4986: Method (_WAK, 1, NotSerialized) Warning 1079 - ^ Reserved method must return a value (_WAK) Any suggestions on how to approach supermicro with this information?
