Getting the above message in dmesg. The system is full of it.
I donot use IPV6 so could not understand the reason for this error. Can you help in resolving it? |

Try adding
to /etc/sysctl.conf. If the file does not exist, create it. Reboot. Then check to see if the messages have disappeared. |

I am using rc-update and not sysctl.
Where in the rc-update does one add this? |

Sorry for the confusion. Try what I said and reboot and report back here the results. It has nothing to do with Openrc or systemd. For example, notice the output on your machine of:
You do not need to post it here. You may notice a line like:
Code: | net.ipv6.mld_qrv = 2 |
What I want to know is if setting this to 1 as I suggested fixes the problem with dmesg.
EDIT:
If you compile your own kernel and do not need the functionality you can try to disable these 2 items in your kernel:
Code: | Networking Support>Networking Options>
<M> 802.1d Ethernet Bridging │ │
│ │ [*] IGMP/MLD snooping |
To see if A) it solves your problem and B) if you have any adverse side effects.
If you use genkernel or another pre-compiled kernel, then your options are to modify the sysctl.conf file as I suggest or as a last resort, using the same file, disable IPv6 entirely. I will not go into the details now. |
