Indeed, that improves the situation. I still need to pass `force=1` to the module to get `/dev/tpm0`. No idea, why it’s not in included in Linux 4.9 yet. ``` $ more /proc/version Linux version 4.11.0-rc5+ (root@d44d03a193d6) (gcc version 6.3.0 20170321 (Debian 6.3.0-10) ) #2 SMP Tue Apr 4 21:07:08 UTC 2017 $ journalctl -k -o cat | grep tpm tpm_tis tpm_tis: 1.2 TPM (device-id 0x3202, rev-id 5) tpm tpm0: Issuing TPM_STARTUP tpm tpm0: [Hardware Error]: Adjusting reported timeouts: A 10000->10000us B 10000->10000us C 0->752000us D 0->752000us $ more /sys/class/tpm/tpm0/device/caps Manufacturer: 0x41544d4c TCG version: 1.2 Firmware version: 11.5 $ sudo tpm_version Tspi_Context_Connect failed: 0x00003011 - layer=tsp, code=0011 (17), Communication failure ``` So do you have an idea, what “ACPI requirements” changed in the `tpm` module since Linux 3.16 to be loaded automatically?
