lirc_serial was ported to rc-core and renamed serial_ir in v4.10. Please look for the different name. Bug is still reproduced for kernel 4.11.0-14-generic x86_64 have you tried: modprobe serial_ir (In reply to Sean Young from comment #1) > lirc_serial was ported to rc-core and renamed serial_ir in v4.10. > > Please look for the different name. After having a look at /lib/modules/4.11.0-14-generic/kernel/drivers/media/rc/serial_ir.ko I noticed that it was referring to linux-hwe-edge-tools-4.11.0-14. I installed this package and its dependencies (libdw1 (0.165-3ubuntu1) and linux-tools-common (4.4.0-92.115)) and the serial lirc device is now recognized and functional. Please note that these packages were not needed with kernel 4.8. linux-tools-common and libdw1 are unrelated to serial_ir.ko. How does it refer to linux-hwe-edge-tools?

I did a "gedit /lib/modules/4.11.0-14-generic/kernel/drivers/media/rc/serial_ir.ko" and line 63 is "\00\00\00\00/build/linux-hwe-edge-HLHSbp/linux-hwe-edge-4.11.0/drivers/media/rc/serial_ir.c\00low\00high\00Serial IR type home-brew\00Serial IR type IRdeo\00Serial IR type IRdeo remote\00Serial IR type AnimaX\00Serial IR type IgorPlug\00serial_ir/input0\00serial_ir\00rc-rc6-mce\00IRQ %d busy" Then I installed this package and dependencies, rebooted and everything came back to normal. |
