[parisc-linux] sstfb crash

[Arjen Hommersom]

Hi,

I just tried to test my Voodoo2 card on a C240 machine. I compiled 2.4.20-pa32 
and set CONFIG_FB_VOODOO1=m. The compiler was 3.0.4. Unfortunately it crashes 
when i try to load it. The following messages appear just before it locks up 
hard:

# modprobe sstfb
sstfb : Voodoo2 with ICS ICS5342 dac
sstfb: framebuffer at 0xf3400000, mapped at 0xf3400000, size 2 Mb
