Apologies if this has been covered in the past, having no luck finding a solution in the search.

 

I'm trying to pass through a USB PCIE Controller into an Ubuntu VM. The device is in it's own IOMMU group. When selecting the device VM Edit window and then booting, the VM fails to boot.

 

I can see the following in the log:

 

Jun  6 05:52:53 Tower kernel: pcieport 0000:00:1c.5: AER: Uncorrected (Non-Fatal) error received: 0000:00:1c.5
Jun  6 05:52:53 Tower kernel: pcieport 0000:00:1c.5: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)

Jun  6 05:52:53 Tower kernel: pcieport 0000:00:1c.5:    [20] UnsupReq               (First)

Jun  6 05:52:53 Tower kernel: pcieport 0000:00:1c.5: AER: device recovery successful

 

Looking at the system devices, the device with the issue here is:

 

[8086:a33d] 00:1c.5 PCI bridge: Intel Corporation Cannon Lake PCH PCI Express Root Port #6 (rev f0)

 

The device that I'm trying to pass through is the following:

 

[1912:0014] 03:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03)

 

I can see that the device is happily bound to the VFIO driver.

 

I have been able to pass through a GPU to another VM in the past so I am fairly happy with settings in the BIOS, just cant figure this bit out.

 

Machine details are:

 

Intel 8700K

Asus Maximus Hero XI (Z390)

Unraid Version 6.10.2

 

Thanks in advance!

pci=noaer

in your syslinux configuration.

I try to pass through RTL8125b  to synologyNAS OR windows11 have same question，the VM fails to boot，syslog show PCIe Bus Error,Have you solved this problem？
