If you want the same modules to load in the vanilla kernel folow steps given below: 1 -boot into the older 4.4.162-78-defaultkernel 2 - change into the vanilla kernel source 4.20.0-rc6 builddirectory 3 - $ lsmod > lsmod.txt 4 - $ make LSMOD="lsmod.txt" localmodconfig Boot into your newly compiled vanilla kernel and run lsmod and smile :-) Hope this helps - Aruna
