P-state tables are probably loaded from separate SSDT tables "CPU0IST" and "CPU1IST". You can download 'em with something like this: # dmesg | grep IST ACPI: SSDT BFD30566, 01FB (r1 PmRef CPU0IST 3000 INTL 20030224) ^addr ^length # acpidump --addr 0xBFD30566 --length 0x1FB > cpu0ist # iasl -d cpu0ist Then paste cpu0ist.dsl somewhere. --D -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
