Hi, I'm seeing this with tun (also with earlier versions): WARNING: at fs/sysfs/dir.c:455 sysfs_add_one+0xb8/0xe0() Hardware name: To Be Filled By O.E.M. sysfs: cannot create duplicate filename '/devices/virtual/net/tun0/group' Modules linked in: microcode dvb_usb_af9015 tda18271 af9013 dvb_usb dvb_core Pid: 3840, comm: openvpn Not tainted 2.6.38-rc4-mm1_64+ #1390 Call Trace: [<ffffffff8106d61a>] ? warn_slowpath_common+0x7a/0xb0 [<ffffffff8106d6f1>] ? warn_slowpath_fmt+0x41/0x50 [<ffffffff81176638>] ? sysfs_add_one+0xb8/0xe0 [<ffffffff8117570d>] ? sysfs_add_file_mode+0x5d/0xa0 [<ffffffff8117575c>] ? sysfs_add_file+0xc/0x10 [<ffffffff81175841>] ? sysfs_create_file+0x21/0x40 [<ffffffff813609d4>] ? device_create_file+0x14/0x20 [<ffffffff813e0256>] ? tun_set_iff+0x3f6/0x4a0 [<ffffffff813e05fe>] ? __tun_chr_ioctl+0x12e/0x5d0 [<ffffffff8126c5c2>] ? __strncpy_from_user+0x22/0x60 [<ffffffff813e0ade>] ? tun_chr_ioctl+0xe/0x10 [<ffffffff811274ed>] ? do_vfs_ioctl+0x8d/0x300 [<ffffffff811277aa>] ? sys_ioctl+0x4a/0x80 [<ffffffff81030dbb>] ? system_call_fastpath+0x16/0x1b
