Line 801. This is very suspicious too. Shouldn't it be returning only
if it is ALREADY enabled?

It returns if it isn't enabled. It was disabled by pnp_enable if that was needed.

My log points to only PCI devices getting enabled. Could this be the
root culprit?

If you put in a debugging statement in pnp_enable_resources you'll see that it gets called too.

Thanks,
