It does:

  https://kernelci.org/boot/id/58b457dc59b514bc145e8e4c/

The problem is not 4.4, but the CONFIG_SMP=n. It also fails with other
kernel versions, and is a bug we need to investigate.

See https://kernelci.org/boot/id/58c2952159b514785a645536/, which is
the same failure, but on 4.9, also due to CONFIG_SMP=n.

I guess it's yet another I/O coherency issue, I'll try to have a look.

Best regards,

Thomas
