Most common cases are Unit > Attentions and TASK QUEUE FULL status. ATA expects the command to be retried as well because a failed flush indicates the specific sector is lost (unless the host still has a copy of course - which is *very* likely although we don't use it) but the rest of the flush transaction can be retried to continue to flush sectors beyond the failed one.
