Well, guys, I got a bunch of new DELL1950's(5), 2650's(4), and 2850's(4)
servers in house to play with today.  Now, all I've got to do is make
them do something intelligent with NetBSD.

First, the changes to the NMBCLUSTERS to correct the problems I was
having when using both bnx0 and bnx1 have corrected the problem  with it
running out of them.  Everything there is fine.

Now, each of these machines has at least 1 Intel PRO/1000 multimode
fiber network card.  Guess what?  When I try to enable one of them, I
get 'fatal page fault in supervisor mode'. Additional statements are
'trap type 6 code 0 eip c05ff9bb cs 8 eflags 10286 cr 2 0 ilevel 6'
'kernel: supervisor trap page fault, code=0'
'Stopped in pid 1368.1 (ifconfig) at netbsd:wm_tbi_mediachange+0xb 
movl 0(%eax),%esi'

Note that I'm copying this off the screen, as I don't have any
capability of capturing this data.

Of course, these machines all have USB keyboards, so once they fault,
there isn't any doing anything except holding down the power button to
reset them.

The problem is related specifically to the fiber cards, as two of these
machines also have Intel PRO/1000 copper connections, and those seem to
work with no problem.
