yes!

Odd. Extremely odd. Does this show on all architectures?
I have tried with different SOC version with same architecture(ARM)and
Synopsys host controller.
I am asking because that is the crucial question.

I see two possibilities

1. the sync probing code has a bug that shows only on some
architectures
2. architectures were a coincidence - the drive is broken

We absolutely need to know what is happening.
Please let me know if I could contribute on this issue.
I would always like to work on it :)

I am afraid this will have to be tested on another architecture.
