PROBLEM: Starting with 2.6.28.5 Core2 Duo CPU T8300 /proc/cpuinforeports different cpu MHz values for processor0 and processor1

Hi Folks,

Starting with 2.6.28.5's ACPI_PDC_SMP_P_HWCOORD patch to include/acpi/pdc_intel.h on a Lenovo Thinkpad T61 (Core2 Duo CPU T8300) /proc/cpuinfo reports different cpu MHz values for processor0 and processor1

Using the performance govenor /proc/cpuinfo's "cpu MHz" line reports different values for processor0 and processor1. processor0 stays locked at 2400 while processor1 fluctuates from 800 to 2400 depending on system load.
I removed the ACPI_PDC_SMP_P_HWCOORD change from a stock 2.5.28.6 kernel and the values re-synchonized.

KEYWORDS: ACPI_PDC_SMP_P_HWCOORD ACPI cpuinfo MHz

both kernel versions exhibit the same problem prior to removing the pdc_intel.h patch introduced in 2.6.28.5 (see http://www.spinics.net/lists/linux-acpi/msg19985.html)
Linux version 2.6.28.5 (root@afterthought) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #2 SMP Fri Feb 20 23:11:44 CST 2009
Linux version 2.6.28.6 (root@afterthought) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #2 SMP Fri Feb 20 22:00:15 CST 2009


here's the patch I applied to 2.6.28.6 to eliminate the discrepancy, though I don't know what it's doing :)
