Any thoughts on this? I know of at least 2 Lenovo models that are running into this problem.
In the case of the one I have currently have access to the problem is that the hash algorithm id for an event isn't one that is currently in the TCG registry, and it fails to find a match when walking the digest_sizes array. That seems like an issue for the vendor to fix in the bios, but we should look at the return value of tpm2_calc_event_log_size and not stick a negative value in efi_tpm_final_log_size.
