Update:

I loaded a bunch of new tracks, and I got put through another FSCK cycle. Now, I know for a fact that I did not do anything that would have left the filesystems dirty. This is on my primary player, and it does not get moved much.

So, I am wondering if the disk check from the latest build is not clearing the dirty flags properly. Immediately after the check completes, I will go and look at the partitions. If what I suspect is true, something will still be marked as dirty or expired.

Note, I have hijack 334 and 2.0 developer on the player, but I have not disabled the fsck timing check through hijack.
