--- Comment #10 from Eugene Savelov savelov@gmail.com --- Having examined linux patch-4.8.3, I found some changes to ptrace API, does wine use it? I found some earlier issues with wine regarding it - could this be related? Can't think of anything else that may affect wine in mostly hardware-related stuff contained in linux kernel patch.
