Most of this I have nothing useful to say about.  But:

Assuming you're using FFS, this is not surprising.  I've seen similar
things on other arches in the presence of anything that takes the
machine down without disk flushing, such as a hard wedge, a power loss,
or a sufficiently nasty panic.

The inode's size is getting updated but (depending on the details)
either the block numbers aren't getting updated, so the file ends with
a hole, or the block pointers are getting written but the data isn't
making it, so you're seeing leftover garbage which happens to be NULs.
