First off, I'd like to say that I'm very, very new to
OpenBSD, and that this is also my first mailing list
message ever, so I'd like to apologize in advance if
(when) I make a really bone-headed mistake(s). So
here's what happened:
Last November, I bought a copy of OpenBSD
4.2(-release). My goal was to install it on an older
i386 machine with a couple decent-sized hard drives
and make it a file (etc.) server with RAID 1. To that
end, I tried to recompile the GENERIC kernel with RAID
support. At the same, I decided it would be good to
update to the 4.2-stable branch, since I had to
recompile anyway. Somewhere along the way, the compile
didn't work, so I thought "maybe -stable isn't for
me", so I tried to do the same with the 4.2-release
code; this failed as well. Then, for the sake of being
thorough, I tried compiling GENERIC with both -stable
and -release sources with the default config file, and
these also failed, and since they all failed the same
way, it appeared to me that it was neither RAID
support nor the -stable branch that was causing the
problem. (Just to be absolutely positive, I've also
reinstalled from both CD and floppy/http, and have
acquired the sources via CD, http, and AnonCVS, and
none of the above made any difference.)
At first I wondered if it was a memory problem (it is,
after all, an old machine), so I ran Memtest86+ for 13
straight hours (7 passes) with absolutely 0 errors.
This was the point at which I knew I was in over my
head, so I brought over a friend who's far better at
programming than I am. He couldn't figure out he
problem, and told me to pass it on to the people who
would know best what's happening with my poor machine.
Following the instructions for updating to the
4.2-stable branch from FAQ 5 (although, as I say, it
doesn't matter what branch I'm compiling from or what
my config file says, the result is the same), I get as
far as 5.3.4, specifically as far as "# make clean &&
make depend && make". While executing 'make depend',
it comes to an item called "swapgeneric.c", which it
sits on for a long time, then pops into the
interactive kernel debugger with the following message
(sorry if I've included not enough/too much
information):
