2.6.23 is over 6 years old.  Why are you using it for new hardware
support?  Note that this code looks very different now.

Plus, from the file number in the crash output, it looks like you're not
dealing with vanilla 2.6.23, as there is no BUG on line 589 of pci_32.c.
If this is Freescale BSP/SDK code, support requests should be addressed
to support at freescale.com or https://community.freescale.com/ -- though
again I suggest going with current upstream code given the age of the
BSP code.

There is a BUG_ON on line 588 -- if it's that one (BUG_ON(rc) after
pci_assign_resource) then look into why pci_assign_resource is failing.

Also please ensure that you have CONFIG_KALLSYMS enabled when submitting
crash dumps.
