Comment 12 for bug 454371

November 26, 2009. I got an automatic upgrade and it killed the lirc remote. So I started trying to solve the problem. It seemed to be the ir_kbd_i2c module. Funny thing... the actual source code is for ir-kbd-i2c (notice the difference between _ and -). Apparently, modprobe does not distinguish these two symbols! In any event the module does not create the /dev/input/event# anymore and gives no indication as to why. I tried to recompile the lirc-0.8.6 package as it has the module but that led to no joy. So I got the v4l-dvb package http://linuxtv.org/hg/v4l-dvb/shortlog/9c38704cfd56 (cx18 package) and compiled it. I had to disable the compilation of the FireDTV module (see Multimedia->DVB/ATSC section of make menuconfig) as there were errors in compiling that module, and I did not need it anyway. Then I did a make install and a modprobe cx18... and everything started working again.

Here is the dmesg output.
