Hi,

Yes I discovered the same issue today on MPC8321E, I plan to look at it 
more closely tomorrow morning (Paris Time).

I think we are missing commit 8183d99f4a22c2abbc543847a588df3666ef0c0c , 
I didn't realise it when we applied the serie to 4.14, 
patch_instruction() is called too early without that patch.

If you have opportunity to test now, you are welcome, otherwise I'll 
test it tomorrow.

Christophe
