Details
On my MacBook Pro 12,1 (A1502) linux-4.9.2 fails to allocate
usb_device. In particular, the keyboard is ignored so I am
unable to login or do anything with my laptop.
On linux-4.8.13 the situation is somewhat better: it takes a while for the kernel to allocate usb_device but it succeeds eventually. So I can login after about thirty seconds. (Much better late than never!) From the kernel ring buffer it looks like xhci_hcd dying has something to do with this... |

Did you try with 4.9.3?
Wow, 4.9.3 actually does fix this isuee. Cheers!
So 4.9.3 worked like a charm but 4.9.4 has the regression again.
There seems to be a race condition somewhere because I cannot
deterministically reproduce this with 4.9.4. I'll close this bug
report until I have something more precise to report.
