Of course it will be great if you can enable CONFIG_ACPI_DEBUG and CONFIG_CPUFREQ_DEBUG in kernel configuration and boot the system with the option of "cpufreq.debug=7 acpi.debug_layer=0x01010000 acpi.debug_level=0x17". After the system is booted, please attach the output of dmesg. Please do the above test on both kernel 2.6.27-rc1 and 2.6.27-rc2.
