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.
