[Linux-fbdev-devel] radeonfb cannot map FB

[Rui S. <rs...@gr...>]

Dear Benjamin Herrenschmidt, dear mailing list subscribers,

     I'm trying to load radeonfb for an RV100 QY chipset. Whatever I
type in the modprobe I always get:
       radeonfb (0000:01:0c.0): cannot map FB
       radeonfb: probe of 0000:01:0c.0 failed with error -5

    I've tried latest 2.6.27.x and 2.6.30.x kernels. This a secondary
video card that I would like to connect a monitor to. The first video
card is an Intel 915G, which is working with vesafb.

    Here is the output of lspci -vvv

    Can you or anyone give a hint on what I might be doing wrong:
modprobe radeonfb mode_option=800x600-16 panel_yres=600
    Or could this be some kind of hardware issue ?

    Thanks a lot for your help,
