You should get a medal!

Hi again!

Yes it seams it was some kind of firmware fault, however I did not have
to update it, it was apparently enough to disable the VT-d feature in
BIOS, doing a cold boot cycle and re-enable the feature again.

I think it's working now but on every boot I get the following
TXT.ERRORCODE: 0xC0000001 which I can't figure out what it means, is
this normal?

Yes it looks like you entered SMX mode successfully. I think that 0xc0000001 code is not really an error - I have ran across it before. Also Jimmy (Gang Wei) from Intel in this thread says the same thing:

"> TBOOT: TXT.ERRORCODE: 0xc0000001
> TBOOT: AC module error : acm_type=0x1, progress=0x00, error=0x0

This just mean everything is ok, sinit executed successfully."

I think you are in good shape :)


The complete log is available on:

Anyway, thank you for your help, I would not have gotten this far
without your response!

        Thank you for quick answer!

        VT-d is enabled in the BIOS.

             $ ls /sys/firmware/acpi/tables
             APIC  ASF!  DBG2  DSDT  dynamic  ECDT  FACP  FACS  FPDT
          HPET  MCFG
             MSDM  SSDT1  SSDT2  SSDT3  SSDT4  SSDT5  SSDT6  TCPA  UEFI1

    Right so it looks like you have firmware issues on this system. You
    should have a DMAR table - it is what describes the VT-d hardware
    and its capabilities. I guess the first step is to see if Lenovo has
    a firmware update.

        There is nothing that look like DMAR in there. I did also a "sudo
        acpidump | grep -i DMA" but nothing intresting showed up.

        Once again, thank you for your quick reply!

                 I'm trying to get tboot to work, but I'm getting
        nowhere fast.

                 I've installed tboot (1.7.4-0ubuntu1 via apt-get) on
        xubuntu 32-bit
                 (kernel 3.11.0-18-generic) on my machine (Lenovo
        Thinkpad Helix

                 Then I put the 3rd_gen_i5_i7_SINIT_67.BIN file in /boot/
                 directory (got
                 it form intel web page).

                 I edited relevant lines in /boot/grub/grub.cfg to look
        like this:

                      submenu "tboot 1.7.4" {
                      menuentry 'Ubuntu GNU/Linux, with tboot 1.7.4 and
                      3.11.0-18-generic' --class ubuntu --class
        gnu-linux --class gnu
                      --class os --class tboot {
                               insmod part_msdos
                               insmod ext2
                               set root='hd1,msdos1'
                               if [ x$feature_platform_search_hint = xy
        ]; then
                                 search --no-floppy --fs-uuid --set=root
                      --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1

                                 search --no-floppy --fs-uuid --set=root

                               echo    'Loading tboot 1.7.4 ...'
                               multiboot       /tboot.gz /tboot.gz
                      logging=serial,vga,memory vga_delay=5
                               echo    'Loading Linux 3.11.0-18-generic ...'
                               module  /vmlinuz-3.11.0-18-generic

        ro  quiet

                               echo    'Loading initial ramdisk ...'
                               module  /initrd.img-3.11.0-18-generic
                               echo    'Loading ACM module ...'
                               module  /3rd_gen_i5_i7_SINIT_67.BIN

                 After this i reboot and select "tboot ..." in grub menu.

                 After displaying "Executing GETSEC[SENTER]..." the machine
                 reboots and
                 on the next attempt I get the following error:

                      TXT.ERRORCODE: 0xC00010c1
                      AC module error: acm_type=0x1, progress=0x0c,

                 I've decoded the error code as per SINIT_Errors.pdf
        from the
                 intel web page:

                      1 - Valid
                      1 - External software
                      000000 - Reserved
                      00000000 - Minor Error code
                      0 - Sotware source
                      00100 - Major error code
                      001100 - Class code
                      0001 - Module type

                 Acording to the pdf this indcates: Class ACPI Check,
        DMAR not found.

                 I have really no idea where to go from here, what do
        you guys

                 I would have included more logs in this message, but I
        only have
                 them in
                 JPEGs since I had to take pictures of the screen to
        save the
                 output. If
                 you think it will help I will attempt to transcribe
        them to text and
                 post a link to pastebin ?

             Do you have VT-d enabled on the system? You will need to
        turn that
             on. If that is not the issue, you could try using acpidump or
             looking in /sys/firmware/acpi/tables to see if your DMAR
        table is
             actually there.

                 Thank you in advance!
