It seems that the commit above has not experienced many test for S3 resume before getting merged.
The default heap size may have to be reconsidered.

A number of libreboot users are also experiencing this, see here: https://codeberg.org/libreboot/lbmk/issues/140
Either disabling Stage Cache, or increasing SMM_RESERVED_SIZE makes the problem go away.
