https://bugzilla.kernel.org/show_bug.cgi?id=218876 Bug ID: 218876 Summary: PCIE device crash when trying to pass through USB Device to virtual machine Product: Virtualization Version: unspecified Hardware: Intel OS: Linux Status: NEW Severity: normal Priority: P3 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: dan@xxxxxxxxxxxxxxxxx Regression: No Hi. I'm running a Debian Bookworm host with Xanmod 6.9.1 kernel This motherboard: https://www.supermicro.com/en/products/motherboard/a2sdi-16c-tp8f With this USB controller in the 4x PCIe slot. https://www.startech.com/en-gb/cards-adapters/pexusb3s2ei The USB card is based on the Renesas uPD720201 USB 3.0 Host Controller and reports the latest firmware. I have a Debian Bookworm VM running on this host, which I intend to pass the entire PCIe card through to (Gnome+Plexamp->USB-SPDIF). If I configure the VM to do this the VM fails to start and I get the following errors from the kernel. The card then becomes seemingly unrecoverable without a warm reboot at least. I have tried many kernel and BIOS options regarding PCIe but nothing has helped so far. I'll attach a boot log. This is the error when I start the VM: May 19 09:24:46 kryten kernel: VFIO - User Level meta-driver version: 0.3 May 19 09:24:46 kryten kernel: xhci_hcd 0000:02:00.0: remove, state 1 May 19 09:24:46 kryten kernel: usb usb4: USB disconnect, device number 1 May 19 09:24:46 kryten kernel: xhci_hcd 0000:02:00.0: USB bus 4 deregistered May 19 09:24:46 kryten kernel: xhci_hcd 0000:02:00.0: remove, state 1 May 19 09:24:46 kryten kernel: usb usb3: USB disconnect, device number 1 May 19 09:24:46 kryten kernel: usb 3-4: USB disconnect, device number 2 May 19 09:24:46 kryten kernel: xhci_hcd 0000:02:00.0: USB bus 3 deregistered May 19 09:24:47 kryten kernel: usb 1-1.2: USB disconnect, device number 4 May 19 09:24:53 kryten kernel: pcieport 0000:00:09.0: broken device, retraining non-functional downstream link at 2.5GT/s May 19 09:24:54 kryten kernel: pcieport 0000:00:09.0: retraining failed May 19 09:24:55 kryten kernel: pcieport 0000:00:09.0: broken device, retraining non-functional downstream link at 2.5GT/s May 19 09:24:56 kryten kernel: pcieport 0000:00:09.0: retraining failed May 19 09:24:56 kryten kernel: vfio-pci 0000:02:00.0: not ready 1023ms after bus reset; waiting May 19 09:24:57 kryten kernel: vfio-pci 0000:02:00.0: not ready 2047ms after bus reset; waiting May 19 09:24:59 kryten kernel: vfio-pci 0000:02:00.0: not ready 4095ms after bus reset; waiting May 19 09:25:04 kryten kernel: vfio-pci 0000:02:00.0: not ready 8191ms after bus reset; waiting May 19 09:25:12 kryten kernel: vfio-pci 0000:02:00.0: not ready 16383ms after bus reset; waiting May 19 09:25:29 kryten kernel: vfio-pci 0000:02:00.0: not ready 32767ms after bus reset; waiting May 19 09:26:05 kryten kernel: pcieport 0000:00:09.0: broken device, retraining non-functional downstream link at 2.5GT/s May 19 09:26:06 kryten kernel: pcieport 0000:00:09.0: retraining failed May 19 09:26:08 kryten kernel: pcieport 0000:00:09.0: broken device, retraining non-functional downstream link at 2.5GT/s May 19 09:26:09 kryten kernel: pcieport 0000:00:09.0: retraining failed May 19 09:26:09 kryten kernel: vfio-pci 0000:02:00.0: not ready 1023ms after bus reset; waiting May 19 09:26:10 kryten kernel: vfio-pci 0000:02:00.0: not ready 2047ms after bus reset; waiting May 19 09:26:12 kryten kernel: vfio-pci 0000:02:00.0: not ready 4095ms after bus reset; waiting May 19 09:26:16 kryten kernel: vfio-pci 0000:02:00.0: not ready 8191ms after bus reset; waiting May 19 09:26:25 kryten kernel: vfio-pci 0000:02:00.0: not ready 16383ms after bus reset; waiting May 19 09:26:43 kryten kernel: vfio-pci 0000:02:00.0: not ready 32767ms after bus reset; waiting May 19 09:27:18 kryten kernel: vfio-pci 0000:02:00.0: Unable to change power state from D0 to D3hot, device inaccessible May 19 09:27:19 kryten kernel: vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible May 19 09:27:19 kryten kernel: vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible May 19 09:27:19 kryten kernel: vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible May 19 09:27:19 kryten kernel: vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible May 19 09:27:19 kryten kernel: vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible May 19 09:27:19 kryten kernel: xhci_hcd 0000:02:00.0: Invalid ROM..
