I could reproduce the problem with a vanilla 2.6.24-rc4 kernel, and it only happens when Smack is enabled. Besides that, I've been told that a similar problem happens with unionfs, but I haven't tried to reproduce it yet. What follows is the output of SysRq+D: """ Showing all locks held in the system: 1 lock held by mingetty/4193: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 1 lock held by mingetty/4194: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 1 lock held by mingetty/4195: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 1 lock held by mingetty/4196: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 1 lock held by mingetty/4197: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 2 locks held by mount.ntfs-3g/4667: #0: (&type->s_umount_key#19){--..}, at: [] sget+0x202/0x350 #1: (&isp->smk_lock){--..}, at: [] smack_d_instantiate+0x39/0x129 1 lock held by bash/4844: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 1 lock held by bash/5389: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 1 lock held by bash/5498: #0: (&tty->atomic_read_lock){--..}, at: [] read_chan+0x1e5/0x605 """ Let me know if you need more information.
