unbinding without X running

I've attached a log of attempt to unbind without X running:

systemctl stop sddm
echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbin=
d ||
true

echo "0000:03:00.0" > /sys/bus/pci/devices/0000:03:00.0/driver=
/unbind

Result is the same but backtrace seems a bit different. This was done with
kernel 5.2.1.

I've tried suspend to ram and another reset bug mitigation (which helps in
other cases), but gpu is still unusable after this failed attempt to unbind=
. I
still can't re-bind it to amdgpu or vfio-pci and clean shutdown is not
happening.
