Lost of pci device even after reboot

[mcdull]

I tried to passthrough a pcie device (USB 3.0 controller) to a vm but failed and resulting a crash to the host. It should have automatically reboot but since then I cannot find the pcie device anymore with lspci.
The vm in question reported fail to start because the pcie assigned is missing.

0a:00.1 Encryption controller: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Cryptographic Coprocessor PSPCPP
0a:00.3 (This item was a USB 3.0 controller but is now missing after soft reboot)
0a:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller

I think power cycle should fix it but the machine is far away from me and if there are any way to fix it I could save some hours of travel time.

My next stage will install a remote control power meter with relay so that I can always powercycle the entire machine remotely, but not at this stage.
Any help would be appreciated.

Thanks.

I though I found some interesting read here.

And the workaround requires kernal patching.
