Controls the kernel’s behavior when a CPU receives an NMI caused by an IO error.
0: try to continue operation (default)
1: panic immediately. The IO error triggered an NMI. This indicates a serious system condition which could result in IO data corruption. Rather than continuing, panicking might be a better choice. Some servers issue this sort of NMI when the dump button is pushed, and you can use this option to take a crash dump.source
