Hi all,

since several days I'm trying to run an ATI 9250 (PCI) graphic card under 
Linux Kernel 2.6.27.19. Nevertheless without success. The kernel shows the 
following message:

videoboot: Booting PCI video card bus 0, function 0, device 7
biosEmu: undefined interrupt 15h called!

radeonfb: probe of 0000:00:07.0 failed with error -5

This is the PCI initialization :

At chipset's MV6450 init, I haven't found any errors. Otherwise an PCI SATA 
controller and an 3Com network card running very well. I have no more ideas, 
where can be the possible problem. Do you have any suggestions?

Best regards
