 Here is the patch which may fix the problem:
 
 http://www.netbsd.org/~rmind/ffs_balloc.diff
 
 It is obtained from FreeBSD (see revision 1.52 and 1.53 of ffs_balloc.c),
 with some minor changes. It looks for me that fail-path could simplified,
 eg. unwindidx could probably be removed. However I do not understand (or
 misunderstand) this code enough to claim anything.
 
 Would be great if some FFS-competent developer would take a deeper look at
 all the logic of this function.
 
 Thoughts?
