- Just to follow up on my own posting, and the thread it seems to be
- going, I can pretty much get the NMI to occur by building the kernel
- over-and-over in a for loop. After a couple of hours - there it is...
-
- It doesn't seem to occur if I let the machine simply sit there for
- days on end (I waited three days.) It seems to occur more frequently
- if I disable the recognition of the match coprocessor in npx.c.
-
- I'm running a kernel w/ Frank Maclachlan's (fpm@crash.cts.com) dma
- fixs and David Greenman's (davidg@agora.rain.com) general file system/kernel
- improvements. With these, the NMI seems to be a little more regular.
-
- Finally, after the NMI, I can now pretty reliably get the following crash
- (from /var/log/messages):

- I'm curious as to what the empty messages could be, and what
- trap type 12 is.... I'm hoping to find the time to wander through
- the sources and figure this one out; but if you know what this is,
- don't hesitate to post.
