Indeed.  I found I had bad RAM while trying to copy files from my
computer to another.  Was using btrfs-send, and it kept failing at
random spots.  At first I thought it was bad files, but after restoring
the affected files from a backup, other random files were affected.  It
seemed no matter what I did, more were going corrupt.  Bad hard drive?
Bad hard drive controller?  But why specific files?

After running memtest, it quickly found the issue.

I dont think ext4.fsck picked anything up.

btrfs gets a lot of crap, but thats the second time it has made me aware
of hardware issues that were leading to bad data.
