I've see many times that SUJ doesnt really make fs clean,
then some problem in fs leads to panics.
And sometimes I boot into single user mode after crash (caused by
other things, eg. page fault), then
fsck_ffs -y ; use SUJ and marked clean, and again:
fsck_ffs -fy ; should not fix anything more, but actually it does
report fixing something
