Hello,
Since the version 4.12 (I also tested with 4.13-rc5) of the kernel, the
tpm device is not showing up in /dev/. In dmesg I can see the following
lines:
[ 1.772153] tpm_tis 00:06: 1.2 TPM (device-id 0x6871, rev-id 1)
[ 1.788106] tpm tpm0: tpm_transmit: tpm_send: error -5
[ 1.788146] tpm tpm0: A TPM error (-5) occurred attempting to
determine the timeouts
[ 1.788194] tpm_tis: probe of 00:06 failed with error -5
[ 1.796865] ima: No TPM chip found, activating TPM-bypass! (rc=-19)
[ 10.085245] tpm_inf_pnp 00:06: Found TPM with ID IFX0102
If I'm reverting to 4.11, everything is working fine.
An idea how to troubleshoot this?
Regards,
Laurent Bigonville
