Hello! I have applied Christoph's full series on top of Linus' tree and I can confirm that the kernel boots fine on my SH-7785LCR board. Thus, for the whole series of patches: Tested-by: John Paul Adrian Glaubitz However, independent of Christoph's series, the kernels throws two backtraces during boot which I think should require a git bisect (unless I missed a configuration option as I trimmed down the kernel a bit to make sure it's not too big). See the traces below and let me know what you think. Adrian ========================================== ## Booting kernel from Legacy Image at 89000000 ...
