These two I've seen before.

And this.

It happens occasionally when you reboot the machine when a device is

BIOS who is supposed to enumerated these devices, I suspect that it is
either problem in BIOS or our PCI enumeration code does something wrong.

This is probably due the previous problem of the PCI device being hidden
behind a bridge.

If you shutdown the machine and boot it without devices connected and
then when the OS is up, connect the device, do you see the same issue?

Also can you try so that you power off the machine completely, connect
the device and power it on. Do you see the issue?

Thanks.
