Current code turns off d-cache first, then flush all levels of cache. This results data loss. As soon as d-cache is off, the dirty cache is discarded according to the test on LS2080A. This issue was not seen as long as external L3 cache was flushed to push the data to main memory. However, external L3 cache is not guaranteed to have the data. To fix this, flush the d-cache by way/set first to make sure cache is clean before turning it off.
