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!

The BIOS uses it to figure out if the OS is compatible with the capabilities of Linux. Unfortunately, the capabilities of Linux are changing over time, and mose BIOS detection of Linux leads to worse behaviour rather than better...

Please file a bug report.
attach the output from acpidump, both dmesg, and the dmidecode output.

thanks,
-Len
