There were a number of bugs in the original openrisc implementation which we have dealt with as well (patches are on their way). We were also hoping to wait for 4.11 to do the move, but I'm updating now to see how this performs with latest on the 4.11 branch.

Now I've done just that it seem to be doing just fine now. Sorry for the noise, we had some initial reports that bumping up was bringing a truckload of other issues, but when I looked at it we only had to change the clock driver slightly. The earlier reports must have been caught up in some other of the openrisc bugs we've corrected on the way.
