[Xorg] xserver: Interrupt pointer (seg f000 off 5490) doesn't point at ROM

[Andreas Kohn]

Hi,

I can't get xserver to run on my machine. Both Xvesa and Xpm2[*] report:

---8<----
andreas at pentium freedesktop.org $
LD_LIBRARY_PATH=/usr/local/freedesktop.org/lib/ sudo bin/Xvesa :0
Interrupt pointer (seg f000 off 5490) doesn't point at ROM

Fatal server error:

Segmentation fault

The card is an Elsa Winner 2000/Office.

The machine in question is a Pentium 200MMX with Linux 2.6.7 (Gentoo).
xserver is built from CVS sources, latest test was yesterday ~2300CEST.


[*] Xpm2 will report this if I force detection:

Should Xpm2/Xvesa work on this card? How could I debug/help debugging
this problem?
