found unsupported CPU with Enhanced SpeedStep

The "invalid ACPI data" suggests that a BIOS update might help. Unfortunately the driver can't do anything for an EST-enabled mobile P4 without the ACPI data.

I don't know too much about ACPI, so I've cc:'d this to the cpufreq mailing list.

Can you make the disassembled DSDT (see http://acpi.sourceforge.net for details and/or http://forums.gentoo.org/viewtopic.php?t=122145 for a howto; proceed until step "7. Diagnosing a Buggy DSDT - Disassemble the DSDT" please) as well as a full dmesg output available on the 'net somewhere, please? If that's not possible, please send these two files off-list to me.

Thanks,
Dominik

Could you please send me those files as well?
I would like much the full acpi dump, since it may be in a SSDT table instead.

wget ftp://ftp.kernel.org//pub/linux/kernel/people/lenb/acpi/utils/pmtools-20031210.tar.bz2 tar xjvfp pmtools-20031210.tar.bz2
cd pmtools-20031210/acpidmp
make
sudo ./acpidmp > acpidmp.out
bzip2 acpidmp.out

Cheers,

Bruno Ducrot

Dominik was pretty helpful. It looks like the _PSD entries are missing from the SSDT table. Many of my errors (and bootup instability) seem to go away when I don't run with hyperthreading on. The processor does seem to scale down the cpu speed but it just doesn't appear to like the interaction between hpyerthreading and speedstep

Here are a bunch of the files I made available to him

Does this contain the ACPI dump you were looking for?

There is four Load statements in the ssdt. I need to look what tables are loaded at run time.

Could you please send to me the result of the attached program when HT mode?

Well, I ran it as root both with HT turned on and off. Both times I got this

CPU0IST 3ffefbe7 277
can't decode CPU0IST
CPU1IST 3ffefb60 87
can't decode CPU1IST
CPU0CST 3ffef988 1d8
can't decode CPU0IST
CPU1CST 3ffef92c 5c
can't decode CPU1IST

Some other comments about HT mode. About 50% of the time when HT is turned on the bootup sequence will oops and hang somewhere. I don't know how to get the output from the oops since it never gets to a single user shell. The rest of the time it will boot up fine and work in SMP mode. The frequency scaling seems to work fine but I get a lot of these messages in my log

acpi-cpufreq: Transition failed

I don't seem to get those when not running with HT on.

Let me know if there is a different program I can run to get those tables

  Matthew Harrell                          There are only 10 types of people in
  Bit Twiddlers, Inc.                       this world: those who understand
  [email protected]                 binary and those who don't.

Well... Originally (before sending you this prog) the latest entry was

        {
                .name = "CPU1CST ",
                .address = 0x40fdd50,
                .len = 100
        },

in order to chekc it worked.

I've taken care that 0x040fd800 is correctly somewhere at the ACPI table:

ducrot@poup$ cat /proc/iomem

     Here...

fc000000-fdffffff : PCI Bus #01
fc000000-fdffffff : 0000:01:00.0

and this worked:

CPU1IST 3ffefb60 87
can't decode CPU1IST
CPU0CST 3ffef988 1d8

so I must admit I'm puzzled.

BTW, its not related, but there is 1Go ram. You should enable highmem in order to get an extra 128Mo.
