Hello List,

finally i built a xserver for my VAXStation 4000/90. But it causes thekernel to dump core (well, on vax it actually doesn't...).After this, i rebuilt everything with DEBUG, got a headcrash, moved toanother town, rebuilt everything again and finally got a debug output ofthe crash.


i applied the patches, which Michael sent to the list.

my mk.conf contains the following lines:
X11FLAVOUR=Xorg
MKX11=yes

my kernel config file and dmesg output is attached.

debug output:
-------------
