This changes produce a panic when unplugging an usb<->ide adapter (it
happens also with 1.133 and 1.334):

kernel; supervisor trap page fault, code=0
Stopped in pid 4.1 (usb0) netbsd:kprintf+0x82b: repne scasb (%esi)
db> bt
kprintf()
print()
usb_disconnect_port()
uhub_explore()

If I back out to 1.131 everything works fine again.
