No, I did not seen this bug before. I noticed it today after systemd update - I grepped /var/log/messages grep drivers/char/tty_io.c messages Oct 21 20:28:53 dio kernel: [ 15.630389] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 20:28:53 dio kernel: [ 16.410427] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 20:45:05 dio kernel: [ 14.682062] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 20:45:05 dio kernel: [ 16.568228] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 20:57:21 dio kernel: [ 14.515496] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 20:57:21 dio kernel: [ 15.976412] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 20:57:21 dio kernel: [ 16.781814] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 21:01:56 dio kernel: [ 14.792913] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 21:01:56 dio kernel: [ 15.902248] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() Oct 21 21:01:56 dio kernel: [ 16.629255] WARNING: at drivers/char/tty_io.c:1325 tty_open+0x29c/0x49b() > I > have a feeling this is going to be a nasty race as a result of the BKL > removal from the TTY code...
