Non-maskable interrupt
Hi, everyone In my system, NMI intrrupt counter is increased continuously, which I found in /proc/interrupts. How can I find the reasons of NMI interrupts? Best Regards Kim. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
