SubjectIntel P55KG motherboard benchmarks, why are the benchmarks slow?
Hello,

This has been discussed in a few forums:
http://www.phoronix.com/scan.php?page=article&item=intel_p55&num=3

Specifically:
[ 0.781758] ACPI Warning: \_PR_.CPU0._PSS: Return type mismatch - found Integer, expected Package 20090521 nspredef-940
[ 0.781763] ACPI: Invalid _PSS data
[ 0.781855] [Firmware Bug]: BIOS needs update for CPU frequency support
[ 0.781897] ACPI Warning: \_PR_.CPU2._PSS: Return type mismatch - found Integer, expected Package 20090521 nspredef-940
[ 0.781900] ACPI: Invalid _PSS data
[ 0.782000] [Firmware Bug]: BIOS needs update for CPU frequency support
[ 0.782040] ACPI Warning: \_PR_.CPU4._PSS: Return type mismatch - found Integer, expected Package 20090521 nspredef-940
[ 0.782044] ACPI: Invalid _PSS data
[ 0.782140] [Firmware Bug]: BIOS needs update for CPU frequency support
[ 0.782180] ACPI Warning: \_PR_.CPU6._PSS: Return type mismatch - found Integer, expected Package 20090521 nspredef-940
[ 0.782184] ACPI: Invalid _PSS data

Could this be the culprit as to why the i870 was so slow during all of the
benchmarks here:
http://www.phoronix.com/scan.php?page=article&item=intel_lynnfield&num=1

While the anandtech article:
http://anandtech.com/cpuchipsets/showdoc.aspx?i=3641

- Shows the new 870 outperforming the 920 in nearly every test?
- Why is the linux performance so poor? BIOS issue?
- Does anyone have any new benchmarks with an updated BIOS?

- Or, are the benchmarks on anandtech taking advantage of new features in
the CPU not available with programs compiled with GCC or is this just due
to the BIOS bug? I suspect the latter, but was curious..

Justin.
