Changed FDivBusyE to stall the whole pipeline. Any instruction in the Executation which depended on the output of an instruction in the writeback stage would be lost if the back end of the pipelined advanced. The solution is to stall the whole pipeline.

Actually fixed the bus width issue coming out of the cache.
...
The root cause is the ahb bus width can be different from LLEN.
If we switch the d-cache to outputing LLEN and on LLEN intervals, subword read needs to operate on LLEN as well.
Then the cache always outputs LLEN data which may need to be muxed down into 2 or more subwords if ABHW is smaller than LLEN.
