Hi Rajiv,
First of all, thanks for your advice. Unfortunately, I can reproduce the
output at will. Even so right after bootup.
As I mentioned in my first e-mail there may be a problem on
BIOS-level already. Therefore, I can't locate the problem in a precise
manner (means whether the TPM is even enabled and active or, later, whether
there is a driver/module problem or even a hardware problem). On one side I
have that bizarre behaviour from BIOS, on the other side I have a correct
dmesg-output but then only those 0x1c error codes.
Best,
-Manuel
