--- Comment #1 from Rafał Mużyło galtgendo@o2.pl --- ...a wacky idea: could it be that whatever steam overlay does, relies on hot-patching functions that could be either in kernelbase or elsewhere, but relies on *all* of those functions being either in kernelbase or elsewhere ?
That is, initial check goes now positive for kernelbase, but as not *all* of the needed functions are in kernelbase yet, hot-patching fails due to those, that are missing ?
