 Replying to [comment:14 axeld]:
 > While I looked over it several times already, I wouldn't rule out a
 memory leak in the block cache. I also have seen a "cache still has
 partial slabs" panic on unmounting BFS recently which might hint into that
 direction, too.

 I can reproduce this panic on unmounting a ReiserFS volume after a larger
 recursive grep (with limited RAM). I've already verified that all
 block_cache_get() calls are balanced by block_cache_put()s. Apparently an
 issue in the low resource handler of the block cache or the slab. Will
 have a look.
