Finally, I got it reproduced at my side with TPM 1.2:

[    0.379677] tpm_tis 00:00: 1.2 TPM (device-id 0x1, rev-id 1)
[   32.453447] tpm tpm0: tpm_transmit: tpm_recv: error -5
[   33.450601] tpm tpm0: Unable to read header
[   33.450607] tpm tpm0: tpm_transmit: tpm_recv: error -62

I'll look at this further after I've sent v6.3 PR.
