Follow-up Comment #1, bug #43601 (project grub): The problem seems to originate during file closure. I added debug logging to grub_file_close, logging messages before the fs close, device close, and file free. I've attached a screenshot of the failure; at first I cat extbootopt without check_signatures set and then cat again with check_signatures set. The device close seems to be the origin of the failure.
