New subject: Running with VGA

      No, Top to down will more worse.
1. I thank Northbridge PCI_DEV(0, 0x18, 0)... should be initial before
CPU....
2. In tree apic cluster is after pci_domain.....

I would change dev_initalize to following
void dev_initialize(void)
{
        struct device *dev;
    printk_info("Initializing devices...\n");

#if CONFIG_CONSOLE_VGA == 1
        for (dev = all_devices; dev; dev = dev->next) {
                if (dev->enabled && !dev->initialized &&
                        dev->ops && dev->ops->init)
                {
                        if( dev->on_mainboard && (dev->rom_address!=0))
continue;
                        printk_debug("%s init\n", dev_path(dev));
                        dev->initialized = 1;
                        dev->ops->init(dev);
                }
        }
#endif
        for (dev = all_devices; dev; dev = dev->next) {
                if (dev->enabled && !dev->initialized &&
                        dev->ops && dev->ops->init)
                {
                        printk_debug("%s init\n", dev_path(dev));
                        dev->initialized = 1;
                        dev->ops->init(dev);
                }
        }
        printk_info("Devices initialized\n");
}
If we really have to do that, I think we should change the init order
to "top to down" instead of "first to last" in the device tree.

It seems after if after cpu init do the onboard vga init, it will work.
The CPU init only do the init ECC and clear that after 1M. ... Werid! And
it
...
is not wiped out after power off.

S2892 has onboard atirage xl
S2895 has no onboard.
With exactly the same chip and BIOS? Then probably the order
of calling device::init() does matter.

No, no problem.
Same addon card (ati rage xl) (pci) on S2895 works well.
I am confused. Are you using S2895 or S2892? And is the rage xl
on board or as an addon card?
