I'm getting this on an admittedly old Toshiba Tecra M9 which supposedly _does_ have an infineon TPM chip. And although tpm_version shows a chip of vendor id IFX to be present and there's a device, trousers or the tpm-tools always claim the device is disabled (after log entries as per OP). /sys/class/tmp/tpm0/device/temp_deactivated has a value of 1 and tpm_infineon is loaded as a module on top of the tpm_tis compiled into the kernel.
I _hope_ _not_ loading tpm_tis would make the chip work with the older tpm_infineon module, but at least (if that doesn't work) loading tpm_tis as a module would allow me to blacklist it and not get the error message. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663904 Title: tpm_tis: a TPM error occurred attempting to read a PCR value To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663904/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
