As I said.
I got this problem when I quit
1/ dt version 1.1.4
2/ X11R6.1 ( xserver.961105.tgz , this one than can beep :-)

I got this problem, for a long time...
I don't have any problem with your GENERIC-1, but I think I began.
to have problem with GENERIC-9 ( I can verify it )

PS: I just try to compile dt without GRF_COMPAT
    I didn't see any change, it crash but without the 2 /netbsd:grfunmap.....
    just "panic:pmap_remove : PA not in pv_tab" :-((
    I think I got a problem . But
       Is there anyone else having the same problem ?
       What can I try to fix it ?
