I read the nmi_watchdog section in http://lxr.free-electrons.com/source/Documentation/sysctl/kernel.txt I tried booting with nmi_watchdog=2 and with nmi_watchdog=1. In both cases I did not see that the NMI interrupts are incremented (cat /proc/interrupts showed 0 0 for NMI) I saw on the web the most new computers from the last 2-3 years should have support for using nmi_watchdog. I am using Fedora 18. (x86_64) I would appreciate if someone (preferably more than one) will try to boot with nmi_watchdog=2 and will report the result. rgs, Kevin _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
