--- Comment #29 from Mike Karels <karels at freebsd.org> ---
Hmm, I see that there are two xhci controllers.  One is on pci7, and I see

pcib7: <PCI-PCI bridge> at device 2.0 numa-domain 0 on pci4
pcib7: failed to allocate initial I/O port window: 0-0xfff
pcib7: failed to allocate initial memory window: 0-0xfffff
pcib7: failed to allocate initial prefetch window: 0-0xfffff
pci7: <PCI bus> numa-domain 0 on pcib7
xhci0: <XHCI (generic) USB 3.0 controller> mem 0xd8000000-0xd800ffff at device
.0 numa-domain 0 on pci7
xhci0: 32 bytes context size, 64-bit DMA
usbus0 numa-domain 0 on xhci0


pcib1: <ACPI Host-PCI bridge> port 0xcf8-0xcff numa-domain 0 on acpi0
pci1: <ACPI PCI bus> numa-domain 0 on pcib1
pci1: <unknown> at device 17.0 (no driver attached)
xhci1: <Intel Wellsburg USB 3.0 controller> mem 0xf6120000-0xf612ffff irq 19 at
device 20.0 numa-domain 0 on pci1
xhci1: 32 bytes context size, 64-bit DMA
usbus1 numa-domain 0 on xhci1
pci1: <simple comms> at device 22.0 (no driver attached)

I'm also not using any USB3 device regularly, so I don't know if the
misbehaving controller is functioning at all.

The messages above are similar with 11.3.
