Public bug reported:
My machine has an Asrock X870E Taichi motherboard. When I was trying to
debug failure to boot properly with the latest BIOS, I noticed a red-
herring error message:
```

for LPM for this host, disabling LPM.

Feb 05 01:03:56 octabrain kernel: hub 12-0:1.0: config failed, hub doesn't
have any ports! (err -19)
```
On my motherboard, this controller seems to be used only for the LED
controller, so it's not critical, but it would be good to get it fixed.
I considered filing it upstream, but the kernel bugzilla says to use the
distro bug tracker first.
