First I am assuming this worked before you tested this patch....

Ok, here we found the two graphics cards in firmware....

Here both the devices were not claimed by the STI driver.

if you look in the register_parisc_driver() in arch/parisc/kernel/drivers.c

you will see that this warning is printed with the driver->probe() function
returns non-zero.

                if (driver->probe(device) == 0) {
                        device->driver = driver;
                } else {
                        printk(KERN_WARNING "Warning : device (%d, 0x%x, 0x%x, 0x%x) NOT claimed by %s\n",
                                device->id.hw_type, device->id.hversion,
                                device->id.hversion_rev, device->id.sversion,
                                driver->name);
                }

The probe function for the STI drive resolves to this function sticore_pa_init()
in drivers/video/sticore.c

I would look at the different inputs/outputs from this function with and without
the patch applied.  I have been trying to duplicate your problem on the 712/100
all day without success *sigh*   I do have a 715 here I can try if you can not
locate the problem, but nothing with dual graphics cards.

Sorry, I do not have a better answer for you *sigh*  


Is anyone else having these problems? I'd like to commit this patch, but I'm
hesitent if it is causing problems.

Thanks,
