This is for a server, so that isn't useful.
I can't understand why the maintainers of vfio don't do a hard reset if
FLR doesn't work.

I've had some success with just suspending my system and then waking
it back up to reset the graphics card (GTX 580). I believe there is a
way to do it directly on the card, but I never got around to setting
it up.

Sometimes when trying to start a VM with a graphics card (nvidia of
course) I receive these errors in dmesg and then I must restart the
entire system to be able to assign that card again as it gets stuck
in S3 mode.
I would like to know exactly how I can hard reset the card so that it
can be usable again, such as killing and then restoring power to the
slot.
