It doesn't matter if this is done in a panic notifier and you're changing that whole shebang or through some other magic. If you do, then this driver needs to *still* *log* those fatal errors - regardless through a panic notifier or some novel contraption it wants to use. So if you want to change the panic notifiers, you *must* make sure those errors still do get logged. Better? -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
