There was a ndiswrapper update released back in October. According to the release note ( https://sourceforge.net/p/ndiswrapper/news/2016/10/version-161-released/ ), it should support kernels up to 4.8, so it should resolve #592064. Removing the compatibility patches for 'newer' kernels from the 1.59 ebuild, this new release compiles and merges, and seems to work with gentoo-sources-4.9.0. Reproducible: Always
