APU2 on 2.9.0 trying to attach to nonexistent Chelsio device

I just updated an APU2 (previously on 2.8.1 without issue) and noticed it is identifying Chelsio hardware and trying to attach. Looking through dmesg, I see:

chvf0: <Chelsio T71400 VF> mem 0xd0526000-0xd05260ff irq 18 at device 19.0 on pci0
chvf0: cannot map MSI-X BAR.
device_attach: chvf0 attach returned 6
chvf0: <Chelsio T72200-RC VF> at device 20.0 on pci0
chvf0: cannot map registers.
device_attach: chvf0 attach returned 6
chvf0: <Chelsio S7450-OCP3 VF> at device 20.3 on pci0
chvf0: cannot map registers.
device_attach: chvf0 attach returned 6

Looking at pciconf, each of these devices is actually:

none2@pci0:0:19:0
AMD FCH USB EHCI Controller
none3@pci0:0:20:0
AMD FCH SMBus Controller
none4@pci0:0:20:3
AMD FCH LPC Bridge

Looks like device matching/probing is going wrong. Any thoughts on this?

@left4pook the forum search is your friend: https://forum.netgate.com/post/124734, FreeBBSd got it wrong.

Yeah looks like a driver bug in the new Chelsio driver. Only real issue is that it breaks the USB2 controller on the APU2. You may need to use a USB3 memory stick to reinstall for example.

Thanks for the USB3 tip.

Oh shoot ... you are right, missed it the first time around.
