Hey guys,
I have a development board based loosely off the MPC8540ADS design that
I am trying to move to the Linux kernel 2.6. I already have this system
working successfully in Linux Kernel 2.4, but after dealing with
compilation and load errors, i've come to the point where I can get to a
console. However, this problem at boot time keeps me from using a lot of
onboard hardware. When I enable PCI support in the Kernel configuration,
this is the text I get at boot time...
PCI: Probing PCI hardware
PCI: Cannot allocate resource region 1 of PCI bridge 1
PCI: Cannot allocate resource region 2 of PCI bridge 1
PCI: bridge 1 resource 2 moved to 9ff00000..9fffffff
PCI: Cannot allocate resource region 1 of PCI bridge 2
PCI: Cannot allocate resource region 2 of PCI bridge 2

PCI: Failed to allocate mem resource #0:1000@0 for 0000:01:06.1
PCI: Failed to allocate mem resource #0:100@0 for 0000:01:06.2
the system is using a PLX PCI bridge chip. Like I said, this works fine
in my 2.4 distribution. Thanks for any and all help!

which 2.6 kernel are you using?

can you post an lspci -v output.
