NFS broken after firmware 4.00?

Same problem here, I can easily copy big file to NAS but when I try to get it back it hangs after copying 2-3 megabytes…

Running 04.00.01-623

Use MyCloud for few days only so can’t say if older firmware have that problem or not, but I’m not sure if firmware is to blame here, my file manager which I use become unresponsive and I simply can’t delete associated processes by any means.

Are those who experience similar bug in the same situation?
