Ok - I recovered my system, and found my ohci problem:

usb 1-3: new full speed USB device using ohci_hcd and address 2

Nothing unusual there.  Then...

ohci_hcd 0000:00:0f.4: Unlink after no-IRQ?  Controller is probably using the
wrong IRQ.

Thats not good... :)

Here's what we have to say about OHCI earlier:

ohci_hcd 0000:00:0f.4: OHCI Host Controller
ohci_hcd 0000:00:0f.4: new USB bus registered, assigned bus number 1
ohci_hcd 0000:00:0f.4: irq 10, io mem 0x10002000

So.. there you go.  I'll explore more on this side and let you know if I see
anything.
