 A bit over a year ago I fixed one msdosfs problem resulting in "buf
 mem pool index 23", but that manifested itself already at mount time.
 It was due to unexpected values in bpb.  I'm pretty sure this one is too.
 
 You should be able to debug the problem fairly easily using rump_msdos
 (but that doesn't exist out-of-the-box on NetBSD 4.0.  It, however,
 should be possible to use rump from -current and fs-utils to recreate
 the problem).  In any case, this PR is a textbook example of why to not
 mount untrusted file system images with in-kernel drivers ...
