Please consider if one core of a multi-core CPU is in system
management mode doing I/O instructions in relation with one specific
device on the system management bus(I2C bus). (This bus exists in ICH7
and there is a PCI device, SMB controller, inside ICH7)

Can other cores of CPU do PCI bus transactions simultaneously? While
one core is doing SMBus I/O transactions?
