Hello !
Before of all I want to make sure that you understand the conditions
here:
I have reinstalled fresh 3.1-RELEASE to the machine in question,
before swapped out two memory DIMM's to the single new 32MB one, just
to be sure it's not some kind of memory error. Installation went
fine, the developer type of installation with full sources but no
games, heh.
Then I downloaded your newest archive for vinum installation:
vinum-4.0-CURRENT.tar.gz from ftp.nanyang-computer.com/pub/vinum/.
It's marked as March 14. Packed it off over the /usr/src and done
compilations in module section and control program section. I also
done make cleandir; make clean in the appropriate directories
several times just to be sure. Compilations went fine and the module
and control program are in the right places with right dates showing
these are newer ones.
Copied the same kernel configuration file as usual to the right place
from backup. Made some minor changes to kernel configuration, removed
DMA support for ata disks, I don't trust the support very much yet.
Made new debug kernel, copied to /var/crash, stripped the original
with -g and installed. Reboot.
Machine goes up, multiuser mode. Right after reboot there are no
modules in loaded. Executed "vinum create stripe.conf", ok. Executed
vinum init, vinum debug 96, vinum saveconfig, vinum printconfig
blabla. All is ok yet.
Newfs -n1 -d0 -v /dev/vinum/rsvol .... two lines newfs output and
crash:

Your access to the machine in question is alive when you need it. I
don't have any clue what's going on, the machine crashes left and
right with vinum under quite light load. Without it I'm able to do
buildworld -j8 without any trouble.
Thanks for your ongoing work
