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

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:

c00f9fb4 t atyfb_get_var
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

  The tdfxfb driver doesn't use resource management yet, as a result both
offb and tdfxfb drive the same card, this might be the cause of your
problems.
