PCI: Cannot allocate resource region 4 of device 00:00.0

So, the 0x10 incrementation is fine, but the agp bus is not working
correctly, and thus the agp graphic card not recognized (and thus no
radeonfb).

That said, i believe the 00:00.0 (should that not be 10:00.0 because of
the renumbering) is the Marvell Discovery II pci controller, and the
actual agp card should be found just behind.

What video card is this ?

A Radeon 9200 SE 64M, from Xpert Vision. The kernel is patched for
Radeon 9200 SE support. (Both i have are Yd models).

It's possible that your config ops for the AGP don't work properly. Make
sure you are really generating type 0 config cycles.

Ok, i will check again, altough no more tonight.

Also, this "cannot allocate resource region" smells bad. Can
you check what the BARs of the host bridge are supposed to mean ?

Ok, will do.

I hope it's not yet another brain dead bridge that puts the system memory
in a BAR... in which case we'll have to "hide" it from linux PCI subsystem.

Mmm, seems  Rob Baxter from Synergy Microsystems are already running
linux on systems with the Discovery II north bridge, so i don't think
this is it. I will check this tomorrow though.

Thanks again for your help,

Friendly,

Sven Luther
