What does HRESULT 0x80280009 (TPM_E_FAIL) mean?

TPM_E_FAIL

The TPM entered a generic failure path

TPM_E_FAIL (0x80280009) means command processing reached an internal failure that is not represented by a more specific TPM 1.2 response. It is therefore important not to replace it with guesses about key policy, storage, or authorization.

Evidence to capture

Capture command ordinal, serialized request/response, resource handles, active sessions, TPM version/firmware, and the immediately preceding command sequence. Check whether the same request fails after a clean, documented state transition.

Focused correction

Reduce the reproduction to the smallest valid command transcript and apply vendor/platform updates only when evidence points to a TPM implementation issue. If a more specific response appears, use that code as the new diagnostic boundary.
