A regression

Hi.

Somewhere between February 23 and today (March 1) something broke my laptop
quite badly:

uhub0 at usb0: vendor 0x8086 UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhub1 at usb1: vendor 0x8086 UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub1: 2 ports with 2 removable, self powered
uhub2 at usb2: vendor 0x8086 UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub2: 2 ports with 2 removable, self powered
uhub3 at usb3: vendor 0x8086 UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub3: 2 ports with 2 removable, self powered
uhub4 at usb4: vendor 0x8086 EHCI root hub, class 9/0, rev 2.00/1.00, addr 1
uhub4: 8 ports with 8 removable, self powered
IPsec: Initialized Security Association Processing.
ahcisata0 port 0: device present, speed: 1.5Gb/s

wd0 at atabus1 drive 0: <HTS541080G9SA00>

So uhub4 disappears in the middle of the boot, causing about a 30 second
delay before the boot proceeds.

Any idea?

PS. This laptop requires PCI_BUS_FIXUP and PCI_ADDR_FIXUP for the cardbus(4)
    and sdmmc(4) to work.
