Also note, if your user has access to serial consoles, and many enterprise users do, then you could also trace an oops. By setting "ftrace_dump_on_oops" in the kernel command line, and have them enable function tracing before they do whatever they do to cause the oops. The ftrace dump output will dump to the console. If they have serial, then it will dump to their serial console where they can record the crash. This information can be very handy for us to analyze and find the cause on an oops. -- Steve _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
