I think you should be able to pre-compile the selftests and save them, and then bisect the kernel further back than their introduction. Actually you may want to simplify the test case to just a mmap/madvise pair and see if that reproduces, since kvm selftests doesn't do much more than that. (Other than all the /dev/kvm ioctls - you have the right perms on /dev/kvm, or are running as root, right?) Thanks, drew
