Description of problem: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/1.3/html/Realtime_Reference_Guide/sect-Realtime_Reference_Guide-Hardware_interrupts-Non_maskable_interrupts.html Second paragraph, second sentence, "...a critical error has ocurred, and...". Additional info: Also, I am not sure if the following (first paragraph of the above link) is correct: "A non-maskable interrupt (NMI) cannot be ignored, and are..." I think the "are" should be an "is". Thanks.
This will be handled as part of the 1.3.2 tech review. LKB
Changed in revision 2.3 to: <para> NMIs are normally delivered over a separate interrupt line. When an NMI is received by the CPU, it indicates that a critical error has occurred, and that the system is probably about to crash. The NMI is generally the best indication of what might have caused the problem. </para> <para> An interrupt is said to be <firstterm>masked</firstterm> when it has been disabled, or when the CPU has been instructed to ignore it. A <firstterm>non-maskable interrupt</firstterm> (NMI) cannot be ignored, and is generally used only for critical hardware errors. </para> Build: Red_Hat_Enterprise_MRG-Realtime_Reference_Guide-1.3-web-en-US-2-3.el5
