That results in 180883 lines (9.2 megabytes) of diff for mlx4.ko. The

Hi. I've upgraded CURRENT from December 19

Loading the OLD mlx4.ko and mlx4en.ko on the NEW kernel actually does
Reverting all mlx4 changes between then and now (no big changes,
mostly just the 1 << 31 thing from D13858) and rebuilding the mlx4
module with CC=clang50 does not help.
Can you do:
objdump -Dx /boot/kernel/mlx4.ko > mlx4.ko.txt
objdump -Dx /boot/kernel/mlx4en.ko > mlx4en.ko.txt
And diff the text result between working and non-working ko's.
Can you open this diff using "meld". And look for instructions which
have changed, not only their location.
