You'll have to wait for a bit. The box that I was debugging takes 45 minutes to reboot. And I don't have much more time to play on it before I have to give it back. I already found the bug I was looking for and I'm trying not to crash it again (due to the huge bring up time). When I get a chance, I'll see if I can insert a trigger to crash the kernel from NMI on another box and see if this patch helps. Thanks, -- Steve
