Hi All,
With acpi_osi=Linux, which dmesg suggested, I got something changed in
the dmesg output(I just listed out the most important things):

It seems with acpi_osi=Linux, it mainly made the two processors equals
in BogoMIPS and made a PCI device window available.
I am not so familiar with ACPI, so can you tell me what is
acpi_osi=Linux used for, and why it made such changes above? Thank you!
