Andrew, I have been doing some work on kgdb to pull a few of it "fingers" out of various places in the kernel. This is the final location where we have a kgdb intercept not covered by a notify. On a related issue, I feel very queasy with sending nmi interrupts and non-nmi events to the same notify code. Would you be open to a patch to create a seperate notify list for nmi events? - George Anzinger george@mvista.com HRT (High-res-timers): http://sourceforge.net/projects/high-res-timers/
