Hmm. Anyway, what kernel are you on? I think I fixed your specific issue in: commit 27747f8bc355a2808ca9e490ab6866acd85b4c16 Author: Andy Lutomirski <l...@kernel.org> Date: Thu Jul 30 20:32:42 2015 -0700 perf/x86/hw_breakpoints: Fix check for kernel-space breakpoints If that does fix it and it's a problem for you on older kernels, you could ask for a backport. --Andy -- Andy Lutomirski AMA Capital Management, LLC
