Right, and logging hw errors from a panic notifier feels simply weird. x86 has its own, special notifier exactly for that and it is independent from the panic path but it gets run right after the exception raised due to the hw error is done. Dunno if ARM has such facilities tho... Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
