A quickly following release of 4.10-rc2 made sure that lirc_dev was loaded
together with serial_ir. However, things still don't work.

I just need to send some codes.
I'm using lirc-0.9.0, which worked fine up to kernel-4.9.1 .

With kernel-4.10-rc1/2 there are two bugs.

1) With the same setup - only the kernel has changed from 4.9 to 4.10 -
   irsend does not work anymore. I get these logs:

Jan  7 01:55:23 localhost kernel: serial_ir: unknown parameter 'debug' ignored

   Where under kernel 4.9 things go well like:

Jan  7 02:25:08 localhost kernel: lirc_dev: IR Remote Control driver registered, major 250
Jan  7 02:25:08 localhost kernel: lirc_serial: module is from the staging directory, the quality is unknown, you have been warned.

Jan  7 02:25:09 localhost kernel: lirc_serial lirc_serial.0: lirc_dev: driver lirc_serial registered at minor = 0
Jan  7 02:25:19 localhost lircd-0.9.0[1970]: lircd(default) ready, using /dev/lircd1
Jan  7 02:25:33 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1
Jan  7 02:25:33 localhost lircd-0.9.0[1970]: removed client
Jan  7 02:25:33 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1
Jan  7 02:25:34 localhost lircd-0.9.0[1970]: removed client
Jan  7 02:25:34 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1

Jan  7 02:25:34 localhost lircd-0.9.0[1970]: removed client


2) lirc-0.9.0 gives me the charming choice of using the lirc-made modules
   (lirc_serial, lirc_dev) or the kernel-made modules (lirc_serial,lirc_dev).
   Now kernel-4.10 ruined things, I should at least have the option of using
   the lirc-made modules instead of serial_ir and lirc_dev.
   However, the modules that lirc makes when using kernel-4.10 do not offer
   the possibily of transmission. (It has no variable txsense anywhere in it.)
   Although compiling says '--with-transmitter', there is something in the
   kernel source that prevents lirc from building that in. That is not
   derived from the .config file it finds in the source. I don't know what
   else it is looking for and doesn't find anymore.

Again no answer and another kernel release, but no fixes.


I just need to only send some codes.
I'm using (gentoo) lirc-0.9.0-rc6, which works fine up to kernel-4.9.2 .

In kernel-4.10-rc1/2/3 there are two bugs.

 1) With the same setup - only the kernel has changed from 4.9 to 4.10 -
    irsend does not work anymore. I get these logs:

 2) lirc-0.9.0 compiled with '--with-transmitter' delivers no transmitter in lirc_serial.ko
