I have an old 755C that I use mostly for word processing at remote
locations (no great loss if something happens to it).  It runs 1.4.2 quite
reliably.  Several times since 1.4.2 was shiny new I have tried to upgrade
it, and it always baulks -- the install never quite works, or the new
kernel conflicts with X, or it just plain crashes.  I find this quite odd,
since my other half dozen or so NetBSD boxes are nearly bullet-proof and
have never complained at upgrade time :-)

Yesterday, seeing that wi 802.11b cards are supported in 1.4.3, I cvs'd
the latest 1-4 kernel source and built a 1.4.3A kernel thinking,if it
looks promising, I'll upgrade the rest later.  The 1.4.3A kernel boots,
finds but does not initialize the wi0 device (ifconfig manually does,
however, boot it), and generally works well for several hours of nonstop
nfs activity.  Today I boot up, it spontaneously reboots after I logged
in, and after I booted a second time and run startx, my window manager
loads only the blank desktop; ctl-alt-backspace and another startx later,
lynx loads one page and locks the entire X display. alt-f2'ing to a fresh
login, I interchange the new 1.4.3A kernel with the old 1.4.2, get a
segfault message, and reboot into 1.4.2, where everything works.

Am I having an unusually bad day, or is there something obviously wrong
with 1.4.3-up on 755c's?
