stress-ng: fail: [5002] stress-ng-aio-linux: io_setup failed, errno=1 (Operation not permitted)
This indicates that the AIO linux io_setup failed with EPERM 1 Operation not permitted error, which is a bit bizarre as the man page does not list that error for that system call. if (io_setup(opt_aio_linux_requests, &ctx) < 0) { pr_fail_err(name, "io_setup"); return EXIT_FAILURE; } Can you run: strace -f stress-ng --aiol 1 --aiol-ops 2 >& trace.log and attach the trace.log to the bug report.
