We should definitely try that.
(I seem to recall that RHEL sets this by default.) Generating an NMI might be another approach for remote reboot -- # sysctl -a | grep panic error: permission denied on key 'net.ipv4.route.flush' kernel.panic = 0 kernel.panic_on_oops = 0 kernel.unknown_nmi_panic = 0 kernel.panic_on_unrecovered_nmi = 0 kernel.panic_on_io_nmi = 0 vm.panic_on_oom = 0
All good - now how do we generate a NMI - by software? Cheers, Michael
