It's strange. I remember xsha512-cuda has already passed TS before I
submited to magnum-jumbo. Even after I implemented loaded hashes/salts
on GPU, it does not stuck. I have to investigated for more.
Previously, other formats passed TS with limited password length, now
they are stuck. Yes, I will investigated on them.

Thanks
