Hi Aaron, Rajob, PeterA and everybody else,

According to the BootDmesg.txt it's an Infineon TPM
[    0.293936] pnp 00:0a: Plug and Play ACPI device, IDs IFX0102 PNP0c31 (active)
[   12.413651] tpm_tis 00:0a: 1.2 TPM (device-id 0xB, rev-id 16)




@PeterA: 
Can you perhaps try find out the exact tpm version?
1) Install trousers and tpm_tools (emerge app-crypt/trousers app-crypt/tpm-tools)
2) Kill the tcsd and run it in the foreground
# pkill -9 tcsd
# tcsd -f
(if it says up and running you can send it to background)
3) Run 
#tpm_version and post the output.



Also the flags etc would perhaps be handy, they can be retrieved via sysfs - on you machine it _should_ be
# cat /sys/devices/pnp0/00:0a/*
and also post the output.


What also might be worth a look - in your bugzilla it states:
[ 0.225891] pnp 00:0a: Plug and Play ACPI device, IDs IFX0102 PNP0c31 (active)
[ 9.150673] tpm_tis 00:0a: 1.2 TPM (device-id 0xB, rev-id 16)
[ 9.292148] tpm_tis 00:0a: Adjusting TPM timeout parameters.
[ 10.084067] tpm_tis 00:0a: A TPM error (7) occurred attempting to read a pcr
value
[ 10.084077] tpm_tis 00:0a: TPM is disabled/deactivated (0x7)


Can you perhaps try to enable your TPM in the BIOS? It's quite often hidden under "embedded security device" or "system security".
Quite often you have to have a bios password set to access these settings.
If your system does not have bios support for TPMs, please tell me so and I'll try to help you out.

Thanks,
PeterH
