** Description changed:
I installed Ubuntu Core (iotg-focal-core-unencrypted-20210804.img) on
the EHL board (CID:202105-29063) and use default BIOS settings.
The boot process stops with the same error as seen when booting Ubuntu
Core on the TGL-H board (https://bugs.launchpad.net/bugs/1938678):
"error locking access to sealed keys: caannot execute hash sequence: TPM
returned an invalid response for command TPM_CC_EventSequenceComplete:
cannot unmarshal response parameters: cannot unmarshal argument at index
0: cannot process list type tpm2.TaggedHashList: cannot process element
at index 3 from list type tpm2.TaggedHashList: cannot process custom
type tpm2.TaggedHash, inside container type tpm2.TaggedHashList: cannot
determine digest size for unknown algorithm TPM_ALG_SM3_256"
