What is the status of this?

I've been experiencing exactly the same get_active_stripe lockup
on a FC5 2.6.17-1.2187_FC5smp  stock kernel. Curiously we have ten 
similar heavily loaded
servers but only one of them experiences the problem. The problem 
happens consistently after 24 hours or so
when I hammer the raid5 array over NFS, but I've never managed to 
trigger it with local access. I'd also
say (anecdotally) that it only started happening since I added a bitmap 
to my array.


As with the other poster, the lockup is released by increasing 
stripe_cache_size.
