Ok, here is the stack backtrace:
I hope it helps, otherwise I could try compiling in frame-pointers. (I used another logger to get this...)
Is it nvidia driver doing something bad (which earlier kernels didn't do)?

If this is the NVidia graphics driver, it's been doing it at least since 2.5.6something,
at least that I've seen. It's basically calling pci_find_slot in an interrupt context,
which ends up calling pci_find_subsys which complains about it. One possible
solution would be for the code to be changed to call pci_find_slot during module
initialization and save the return value, and use that instead. Yes, I know this
prevents hotplugging. Who hotplugs graphics cards? ;)
