Looks like reiserfs has some locking problems:
=============================================
[ INFO: possible recursive locking detected ]
2.6.20-mm2 #6
---------------------------------------------
beagled/4786 is trying to acquire lock:
(&inode->i_mutex){--..}, at: [<ffffffff80479df9>] mutex_lock+0x19/0x20
but task is already holding lock:
(&inode->i_mutex){--..}, at: [<ffffffff80479df9>] mutex_lock+0x19/0x20
other info that might help us debug this:
3 locks held by beagled/4786:
#0: (&inode->i_mutex){--..}, at: [<ffffffff80479df9>] mutex_lock+0x19/0x20
#1: (&REISERFS_I(inode)->xattr_sem){----}, at: [<ffffffff80304c99>] reiserfs_setxattr+0x79/0x150
#2: (&REISERFS_SB(s)->xattr_dir_sem){----}, at: [<ffffffff80304cc0>] reiserfs_setxattr+0xa0/0x150
