   Hi @mseth10 ,
   
   - Could you confirm whether convolution-only tests pass, if it using ACL and 
paste those logs here for reference by setting DNNL_VERBOSE=1 ?
   - For the deconvolution tests, it seems like it is calling the reference 
deconvolution but also calling the ACL implementation during the forward pass. 
I had a look at `test_deconv` 
https://github.com/apache/incubator-mxnet/blob/40359ceda150ca75da6e45b1ea35d747ef53deac/tests/python/unittest/test_gluon.py#L451
 and it looks like it is calling `check_convolution_forward()`. As a 
confirmation, is the following test (`check_deconvolution_forward_backward`) 
passing? 
https://github.com/apache/incubator-mxnet/blob/40359ceda150ca75da6e45b1ea35d747ef53deac/tests/python/unittest/test_operator.py#L1086.
 Is it calling ACL during the forward pass and oneDNN reference in the backward 
pass? OR is calling reference in both forward and backward?  If the test is 
passing, then it might be a peculiarity  of the test itself rather than an 
integration issue. Either way, it might be worth understanding what this gluon 
test_deconv is actually doing.
