[vfio-users] GTX 580 Passthrough - Successes and Failures

[Ben J]

I'm still having ROM errors after checking all of those switches and
removing the SLI cable? I also have occasional issues where when I try to
suspend the computer just immediately wakes back up, failing to reset the
card. I'm assuming something is holding the computer back from powering
down. It's strange stuff, I might see if I can just use poweroff to reboot
the card directly.
