Hello,

   I Just installed armbian in my cubieboard and dmesg is showing an annoying message:

[   70.366543] rc rc0: IR event FIFO is full!
[   70.382773] rc rc0: IR event FIFO is full!

[   70.552683] rc rc0: IR event FIFO is full!

 

   I did a search on forum and havent find anything related to this error:

   This is some usefull info:

root@cubieboard2:~# cat /etc/armbian-release
# PLEASE DO NOT EDIT THIS FILE
BOARD=cubieboard2
BOARD_NAME="Cubieboard 2"
VERSION=5.20

root@cubieboard2:~#

 

  And finally here is a link for armhwinfo.log:  http://sprunge.us/eGhd

 

 

 

 

I guess it must be some glitch in IR driver? To stop this flood try to blacklist the IR module.

Hi Igor,

   Thanks for your repply, so this is what i Did:

   First checked with lsmod, loaded modules:

root@cubieboard2:~#

Added the modules to blacklist:

 

 

root@cubieboard2:~# cat /etc/modprobe.d/blacklist.conf  | grep ir
# most apps now use garmin usb driver directly (Ubuntu: #114565)
blacklist ir_lirc_codec
blacklist lirc_dev
root@cubieboard2:~#

 

Updated initramfs:

root@cubieboard2:~# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.7.3-sunxi
root@cubieboard2:~#

Rebooted....

But still lsmod show me those modules:

root@cubieboard2:~# lsmod

sun4i_codec            11391  3

uio                     8000  1 uio_pdrv_genirq

So for now, i just unloaded them manually, if it works i will try to find out a permanent sollution, so for now thanks  

 

root@cubieboard2:~# rmmod ir_lirc_codec
root@cubieboard2:~# rmmod lirc_dev
[  242.258275] IR MCE Keyboard/mouse protocol handler initialized
[  242.297565] IR XMP protocol handler initialized
[  249.871891] lirc_dev: module unloaded

 

 

OK. Try blacklisting evdev or remove ir from device tree.

 

I know it's annoying but I think it's safe to ignore ... until next update. Will pay attention to this.

So for the sake of information had to disable these modules:

 

blacklist ir_lirc_codec
blacklist lirc_dev
blacklist evdev
blacklist sunxi-cir

 

The reason i didit was because the board was hanging after a while (4 or 6 hours) after disabling those  im already at 17Hour uptime Thanks

I've followed this post to remove that messages, too - and after blacklisting the 4 modules Lucas recommended in the last reply I realized that the power button has stopped working!

 

In order to keep the power button working I had to remove the evdev mode from the blacklist. The button started working again and the FIFO error messages are still not showing up.

 

Not sure about possible other consequences of this  , but for now this is enough for me

 

Thanks!

Are there any news on an "official" solution on this?

I'm updated to 5.23 on a cubietruck and also/still have this problem. I will try to blacklist the modules too ...

I've found this patch, but not tried, because now I have no need for LIRC:

https://patchwork.kernel.org/patch/7715591/

This bug is still in debian version used in armbian 5.38.

 

cat /etc/armbian-release
# PLEASE DO NOT EDIT THIS FILE
BOARD=bananapi
BOARD_NAME="Banana Pi"
BOARDFAMILY=sun7i
VERSION=5.38
LINUXFAMILY=sunxi
BRANCH=next
ARCH=arm
IMAGE_TYPE=stable
BOARD_TYPE=conf
INITRD_ARCH=arm
KERNEL_IMAGE_TYPE=zImage
 

Tentative to solve it, only by creating the file bellow and reboot.

 

cat /etc/modprobe.d/blacklist.conf
blacklist ir_lirc_codec
blacklist lirc_dev
blacklist sunxi-cir
 

Just one hour up and no more FIFO is full message.
