Created attachment 22073 [details] the dmesg log on the 2.6.30-rc4 On some boxes several processors use the same processor bus id.But they are located in different scope. For example: \_SB.SCK0.CPU0 \_SB.SCK1.CPU0 As they use the same bus id, OS will complain the OOPS when registering the acpi proc I/F for the processors that use the same bus id.
