Sorry for the delay, now got some minutes to test your patch and
indeed it makes the kernel pass the old stuck point:

  [...]
  root on wd0a dumps on wd0b

  /dev/rwd0a: file system is mounted read-write on /; not checking
  Setting tty flags.
  Setting sysctl variables:

but later (my qube is a heavy loaded machine ;-)) it crashes (at
starting swapping?):

  [...]

This reproducable crash(es) were the other reason for writing the pr.

Any more info I can provide?
