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

   root file system type: ffs
   pid 1(init): ABI set to O32 (e_flags=0x1007)

   Starting root file system check:
   /dev/rwd0a: file system is clean; not checking
   swapctl: adding /dev/wd0b as swap device at priority 0
   Starting file system checks:

   /dev/rwd0f: file system is clean; not checking
   /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?
