The problem was seen on a 2015 XPS-13 with a Nuvoton TPM that was software upgraded to 2.0 (and had several other problems because of this). I assumed, based on the lack of reports from others, that this was a problem specific to my TPM and so didn't push it. The annoying thing for me was that the TPM didn't seem to recover. Once it started giving timeouts it carried on timing out until machine reset, which really caused problems because all my keys are TPM resident. Is yours a permanent problem like mine, or is it transient (TPM recovers and comes back)? Regards, James
