I am missing patches like x86/pti: Switch to kernel CR3 at early in entry_SYSCALL_compat() x86/pti: Make sure the user/kernel PTEs match in 4.9. The first one was really important but the problem might be hidden now due to x86/cpu, x86/pti: Do not enable PTI on AMD processors -- Regards, Thomas Deutschmann / Gentoo Linux Developer C4DD 695F A713 8F24 2AA1 5638 5849 7EE5 1D5D 74A5
