Prometheus PCI Driver

[Adam K. <ako...@co...>]

Hi,

So far so good on the 2.4.17 version of the Prometheus PCI driver.  I'm down
to one message during the PCI initialization that I'm not too sure of what
it means.  I'm not sure what the following is telling me:

> PCI: Cannot allocate resource region 1 of PCI bridge 0

If I take a look at /proc/iomem, there are clearly entries for the resource
that I've set up for the PCI memory and entries for the Voodoo 3 card show
up as well.  Similarly, /proc/ioports shows the I/O port listing for the
Voodoo 3 I/O port.  Here is the dmesg file for reference.  Any ideas what
the message means?

Adam
