Sorry it took me a while to get to this again. I had to write some papers 
on the machine and didn't want to tie it up compiling the system.
The error I get seems to be reproducable for me and this time I didn't
delete the .core files :-)
To the configuration :
Q700, 20MB Ram, 2MB Video (at 256 greys), MacCon Nubus Ethernetcard, HD.

After doing a make build again on the 1.3.1 sorces and waiting for about 
26 hours I exited from single user and the system seemd to come up fine.
I could log in from console. Starting the xdm was when the problem 
occured again. Ken's Xmac68k.OSFA server duped core, gdb gives:

#(gdb) core Xmac68k.core
#Core was generated by `Xmac68k'.
#Program terminated with signal 11, Segmentation fault.
#Cannot access memory at address 0x40a0.

and the xdm-errors:
#/usr/libexec/ld.so: warning: libc.so.12.20: minor version >= 25 expected, 
#using it anyway
#/dev/grf0: Couldn't get video mode information via ROM driver.
#        This is not a fatal error.
#        I gather there is no ROM driver support for this screen...
#        I will treat this screen as StaticGray or TrueColor.
#Screen 0 at 0x423ae00, 1152 by 870, 8 bpp, rowB 1152, fbbase 0xf9000000.
#xdm error (pid 25292): IO Error in XOpenDisplay
#xdm error (pid 25287): Display :0 cannot be opened

Reinstalling the base.tgz got everything working again.
May I not use the -O2 -m68040 options on compilation time ?
I was hoping for a little more speed, as I do have to run quite a few 
haevy workloads on this poor old Quadra.

Will it help doing just a -O -m68040 build or to omit the -m68040 ???
I'd be thankfull for any help

humbly
Henning
