PCI Resource Collisions & qla1280

PCI Resource Collisions & qla1280

[Kumba]

Anyone got any tips on debugging a cranky SCSI adapter that's not getting 
initialized due to resource collisions?  e.g.,

qla1280: QLA1040 found on PCI bus 0, dev 0
PCI: Device 0000:00:00.0 not available because of resource collisions
qla1280: Failed to enabled pci device, aborting.
qla1280: QLA1040 found on PCI bus 0, dev 1
PCI: Device 0000:00:01.0 not available because of resource collisions
qla1280: Failed to enabled pci device, aborting.


This happens on 2.6.13.4 on an SGI Origin (IP27).  2.6.12.5 seems to have better 
luck; actually seeing the drives/partitions, but gets stuck on something (unsure 
what), then issues several adapter/bus resets and either oopses or continues on 
normally.  Rather than focus on 2.6.12.5's oddities, though, I figured better to 
take a stab at 2.6.13.4.  Unsure if it's entirely mips-specific (probably is), 
but I can't seem to find any changes in git that would immediately stand out as 
being the cause.
