Well, seems like everyone else is having a _very_ hard time reproducing
this problem...

...and you're not giving us much to go on :-)  There isn't a kmem_suballoc()
call anywhere near line 740 of machdep.c.  That line is in identifycpu().

So, does it die on:

	buffer_map?
	exec_map?
	phys_map?
	mb_map?

How far into kmem_suballoc() does it get?

printf() is your friend :-)

In case you typo'd that line number, and really meant 640, it's possible
that you're losing because you've bumped NBUF, or something, and kernel_map
doesn't have enough space for the submap.  (I say that because buffer_map
is the first submap allocated :-)
