I'm having a little trouble with NetBSD/sun3.  It's not the usual
swap-over-NFS trouble, though. :-)

I'm doing a full rebuild (ie, as if "cd /usr/src ; make build").  But
it died twice so far, with peculiar behavior.  The first time, there's
just an unexpected "Segmentation fault - core dumped" in the logfile,
accompanied by a make.core appearing (and the make failing); however,
on the console at the same time, I got

	si_dorequest: target=0, lun=0, resetting...

The console message has appeared twice more to date.  One time it had
no visible effect on the build; the other time it produced "echo: not
found" and the make crashed at that point.

Is this just a symptom of an old kernel, which I should just put up
with until I get the kernel rebuilt, or is it something worse?  The
kernel dates from late July.  dmesg output follows.  (Since I don't
have bootblocks on that disk yet, I booted oddly.  I told the ROM to
boot from ie(), told (SunOS) network boot to use root on nfs and to
boot netbsd -as, and told the kernel to run with root on sd0a swap/dump
on sd0b.  And yes, I made sure /netbsd on disk was identical to the
kernel I actually booted from.)  The message about ie0 occurred where
it did because I didn't bring up the network until I needed it to get
logfiles onto a machine I could send this letter from.
