kernel panic starting XFree86 4.0.1 / Voodoo3 on 2.4-test9 -

[phandel at cise.ufl.edu]

I have been successfully using Ani's penguinppc.org::xfree86-pmac tree
with my Voodoo3 card with a stable 2.2 series kernel (from
ppc.samba.org::linux-pmac-stable, with the voodoo3 driver from the 2.3
series).  Today I tried the 2.4-test9 kernel from
ppc.samba.org::linux-pmac-devel and got the following panic while trying
to startx:

>From the System.map:

c00fa018 t atyfb_set_disp
c00fa17c t atyfb_set_var
c00fa388 t atyfb_pan_display
c00fa410 t atyfb_get_cmap
c00fa500 t atyfb_set_cmap


When I tell XFree86 to use the ATI card instead (via "Screen 1" instead
of "Screen 2" at the end), it works fine.


Thanks,
Peter
