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: bridge 2 resource 2 moved to 9fe00000..9fefffff PCI: Cannot allocate resource region 1 of device 0000:00:14.0 PCI: Cannot allocate resource region 2 of device 0000:00:14.0 PCI: Cannot allocate resource region 0 of device 0000:01:01.0 PCI: Cannot allocate resource region 1 of device 0000:01:01.0 PCI: Cannot allocate resource region 2 of device 0000:01:01.0 PCI: Cannot allocate resource region 0 of device 0000:01:05.0 PCI: Cannot allocate resource region 1 of device 0000:01:05.0 PCI: Cannot allocate resource region 2 of device 0000:01:05.0 PCI: Cannot allocate resource region 0 of device 0000:01:06.0 PCI: Cannot allocate resource region 0 of device 0000:01:06.1 PCI: Cannot allocate resource region 0 of device 0000:01:06.2 PCI: Failed to allocate mem resource #0:1000000@0 for 0000:01:01.0 PCI: Failed to allocate I/O resource #1:100@1000 for 0000:01:01.0 PCI: Failed to allocate mem resource #2:1000@0 for 0000:01:01.0 PCI: Failed to allocate mem resource #0:10000@0 for 0000:01:05.0 PCI: Failed to allocate mem resource #2:10000@0 for 0000:01:05.0 PCI: Failed to allocate mem resource #0:1000@0 for 0000:01:06.0 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! Clinton Thomas cthomas@soneticom.com
