The point is, this can happen every time the kernel crashes, and reiserfs
wrote something to it's metadata logs (or so I gather from your and Alan's
explanation). And apart from my source files getting randomly distributed,
reiserfs works like a charm (I have a Dell as well, and it used to crash a
lot, which was the main reason for me to switch to reiserfs in the first
place), is fast, and stable. I like it a lot, but not on a machine where I
do my development on, nor a machine without a UPS. It just doesn't help
not knowing if/when a file gets corrupted/wrongly distributed/written

It looks to me (with all my ignorance) that reiserfs shuffles it's blocks
a lot when writing back, and that bites when something interrupts it.
I can't back that up with code, put my finger to it or anything else, but
that's my take on my problems.
