NetBSD and xserver and core dump and no drivers

[Jeremy C. Reed]

I have no drivers installed (yet).

On NetBSD/i386 3.99.18 (-current), latest Xorg core dumps. The log has:

(II) PCI-to-ISA bridge:
(II) Bus -1: bridge is at (0:17:0), (0,-1,-1), BCTRL: 0x0008 (VGA_EN is 
set)
(--) PCI:*(1:0:0) unknown vendor (0x1106) unknown chipset (0x3122) rev 3, 
Mem @ 
0xd8000000/26, 0xde000000/24, BIOS @ 0xdfef0000/16

   *** If unresolved symbols were reported above, they might not
   *** be the reason for the server aborting.

Fatal server error:
Caught signal 11.  Server aborting

Xorg should close cleanly without coredump when it detects a problem.

p.s. Maybe the Version and Release Date should be updated for the current 
(MAIN) code so it is not misleading.

p.p.s I will install some drivers now ...
