Noticed that there's some new thunderbolt code. I get this during boot:
pci3: <PCI bus> on pcib3
nhi0: <Generic USB4 NHI> at device 0.0 on pci3
nhi0: Cannot find Upstream Facing Port
nhi0: tb_router_attach_root() error. The driver should be loaded at boot
If it helps any, here's some "pciconf -lv" output snippets:
pcib2@pci0:1:0:0: class=0x060400 rev=0x02 hdr=0x01 vendor=0x8086 device=0x
1136 subvendor=0x8086 subdevice=0x0000
vendor = 'Intel Corporation'
device = 'Thunderbolt 4 Bridge [Maple Ridge 4C 2020]'
class = bridge
subclass = PCI-PCI
pcib3@pci0:2:0:0: class=0x060400 rev=0x02 hdr=0x01 vendor=0x8086 device=0x
1136 subvendor=0x8086 subdevice=0x0000
vendor = 'Intel Corporation'
device = 'Thunderbolt 4 Bridge [Maple Ridge 4C 2020]'
class = bridge
subclass = PCI-PCI
pcib4@pci0:2:1:0: class=0x060400 rev=0x02 hdr=0x01 vendor=0x8086 device=0x
1136 subvendor=0x8086 subdevice=0x0000
vendor = 'Intel Corporation'
device = 'Thunderbolt 4 Bridge [Maple Ridge 4C 2020]'
class = bridge
subclass = PCI-PCI
Can include more if needed. System works fine without whatever it's
trying to do (of course, since it wasn't even detected before :-) )
