It crashes with a "trap" -- I have a picture here of the crash,
transcribed for your pleasure:

uvm_fault(0xffffffff809f82c0, 0xffffff8000506f0000, 1) -> e
fatal page fault in supervisor mode
trap type 6 code 0 rip ffffffff80366f48 cs 8 rflags 10202 cr2
ffff800056f0000 cpl 0 rsp ffff80005064b950
kernel: page fault trap, code=0
Stopped in pid 7503.1 (random-feed) at  netbsd:rndpool_add_data+0x40:
xorl 0
(%r9),%ecx

I'm running NetBSD 5.1 according to uname -a:

explorer@not:~> uname -a
NetBSD not.flame.org 5.1 NetBSD 5.1 (GENERIC) #0: Sat Nov 20 17:35:12

CVS/Entries has this for these two files:

/rndpool.c/1.20/Mon Apr 28 20:23:47 2008//Tnetbsd-5
/rnd.c/1.71.4.2/Tue Nov 24 21:28:27 2009//Tnetbsd-5

And here is the output of a diff for them:

explorer@not:/usr/src/sys/dev> cvs diff -u -r HEAD -kk rnd*
explorer@not:/usr/src/sys/dev>

I don't know how much more certain I am running 5.1 and that the same
file is on HEAD as on the netbsd-5 branch I can be without having you
provide me a kernel to run.  :)
