Copy/pasting from my response to the other thread at https://lkml.org/lkml/2013/1/15/440 ==== Thorough and careful review and analysis revealed that the rootcause very likely is that I am a complete nitwit. Could you please try the patch below and report backt? Thanks. From: Jiri Kosina <jkosina@xxxxxxx> Subject: [PATCH] lockdep, rwsem: fix down_write_nest_lock() if !CONFIG_DEBUG_LOCK_ALLOC Commit 1b963c81b1 ("lockdep, rwsem: provide down_write_nest_lock()") contains a bug in a codepath when CONFIG_DEBUG_LOCK_ALLOC is disabled, which causes down_read() to be called instead of down_write() by mistake on such configurations. Fix that.
