By this I hope you mean 2.1.12, since 2.0 is really done except
for security updates.  For what its worth, a number of locking issues have
been solved in the 2.1 tree.

I've never seen it before in that version, 2.0.16 was pretty stable.  It
seems strange to me that the processes that are getting stuck will move.
Are they trying to acquire a lock on some other file?  If so, what is it?

Generally in a deadlock situation, killing the stuck process should
resolve the problem, so this seems like more of a kernel issue to me but I
wouldn't want to place the blame there prematurely.
