I have the same issue with bbswitch (and maybe vgaswitcheroo too). Basically
this means that in d3cold we can't talke to the gpu and the information isn't
cached or something like that.

I will not be able to test until later this afternoon. I have a GTX 960 as
PCI 01:00.0 and GTX 730 as PCI 02:00.0.
I will send over dmesg/journalctl -k.

Thanks Rashed. This looks better but something seems to be going wrong with
PCI. I'm pretty clueless about PCI/ACPI, so let's see if someone else has
something to suggest...

dmesg using tentative fix

Alexandre, using the tentative fix you uploaded it switches GPUs properly now.
Here is the dmesg from that since there are still some errors related to power
state in it. Also, for some reason lshw is returning this for the nVidia GPU
now:

*-generic
description: Unassigned class
product: Illegal Vendor ID
vendor: Illegal Vendor ID
physical id: 0
bus info: pci@:01:00.0
version: ff
width: 32 bits
clock: 66MHz
capabilities: bus_master vga_palette cap_list rom
configuration: driver=nouveau latency=255 maxlatency=255
mingnt=255
resources: irq:129 memory:dc00-dcff
memory:b000-bfff memory:c000-c1ff ioport:e000(size=128)
memory:dd00-dd07

I don't know if that's related to this at all but before, if I set runpm=0 and
run lshw, it would return the proper description (running it without runpm
would cause the system to hang)
