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,

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

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

  http://alecto.bittwiddlers.com/files/inspiron-5160/dmesg

  http://alecto.bittwiddlers.com/files/inspiron-5160/ssdt.dat
  http://alecto.bittwiddlers.com/files/inspiron-5160/ssdt.dsl

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

        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

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 
00000000-0009f7ff : System RAM

     Here...

  fc000000-fdffffff : 0000:01:00.0

and this worked:

CPU1IST  3ffefb60 87

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.
