This type of error is usually the result of the kernel not disabling the DMA
protection put in place by tboot. You need to specify 'intel_iommu=on' on the
kernel command line. That said, if the kernel is built with CONFIG_INTEL_TXT
then it should automatically enable intel_iommu, which leads me to think that
this kernel has not been built with TXT support.

Subject: Re: [tboot-devel] tboot on Ubuntu 10.10/ Linux kernel 2.6.38 32 bit
Thanks for the reply Mike.
Yes, I am able to boot 32 bit 2.6.38 kernel without tboot using the following
grub.cfg entry:
menuentry "Ubuntu, with Linux 2.6.38-020638-generic (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set
154e4bc5-aa94-4e1d-9f1c-e6c5cda3ed38
linux /boot/vmlinuz-2.6.38-020638-generic
root=UUID=154e4bc5-aa94-4e1d-9f1c-e6c5cda3ed38 ro quiet splash
initrd /boot/initrd.img-2.6.38-020638-generic
}
I don't believe that the ERRORCODE got assigned any value at all during the
tboot booting on 32 bit configuration. That's just being the log from last
successful tboot boot on 64 bit configuration.
The whole thing is strange because, I am able to boot with tboot on exact same
hardware configuration but using 64 bit Ubuntu dist and 64 bit kernel.
Anyway thanks again,
Cheers
Sansar

Hello everybody
I have a problem with booting with tboot on Ubuntu 10.10 (32 bit)/ Linux kernel
2.6.38 (32 bit).
I succeeded booting on same hardware but on 64 bit Ubuntu 10.10 and 64 bit
2.6.38 kernel.
Now the problem is, TBOOT hangs on the screen on which I could see the
following, then I've to power down to boot again.
...
TBOOT: VMXOFF done for cpu 1
TBOOT: cpu 1 is waking up, SIPI vector=9b000
TBOOT: VMXOFF done for cpu 4
TBOOT: cpu 4 is waking up, SIPI vector=9b000

TBOOT: cpu 5 is waking up, SIPI vector=9b000

Could somebody help me further on?
Thanks in advance

I've the following set of hardware:
Intel DQ57TM board (with q57 Chipset) and Core i5 660 processor.
I've updated my BIOS to the latest available version of 22.03.2011.
I've enabled TPM, VT-d, TXT enabled in BIOS and taken ownership of my TPM with
well known passwords.
The following is the output I was able to get using tboot/utils/txt-stat after
power down and boot without tboot:
Intel(r) TXT Configuration Registers:

It looks like the measured/verified lanuch succeeded based on this ERRORCODE.
The problem is further down the line.

Following is the entry in my grub.cfg :
menuentry "Ubuntu, with Linux 2.6.38-020638-generic with tboot (on /dev/sda1)"
{
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
This line looks strange to me (I'm not saying it's wrong). My root device is
always ext2 not msdos and is set like this:
insmod ext2
set root='(hd0,1)'
Are you able to boot your 32-bit kernel without tboot? What does that grub
menuentry look like?
Good luck,
-Mike
