--- Comment #2 from Vladislav Movchan <vladislav.movchan at gmail.com> ---
I suppose this problem (panic: Freeing unused sector) might be caused by the
same reason described in bug 213507.
I.e. in directories with the large amount of files (directories which occupy
more than one cluster) garbage-like directory entries could appear.
Attempt to interpret such dentries (which are basically random data) could lead
to unexpected results.

Could you please try to reproduce this on CURRENT after base r333693?
To reproduce this problem myself I tried to create several hundreds of
directories with 500 to 1000 small files in each and removing them all at once.
I repeated this procedure multiple times but was not able to trigger this on
r333698.
