Great thanks, can you also run this with taskset to bind to
a single CPU,
# taskset 0x1 ./pifof_stress.py
And let me know if you still see the OOO.
Interesting. Looks like it depends on which core it runs on. CPU0 is
clean, CPU1 is not.
So we are at v4.16-rc6 now - have you managed to reproduce this is or
should I try to get the revert correct?
Best regards,
Jakob
