Comment 0 for bug 988183

Hi,

I am observing a lot of "ICMPv6 RA: ndisc_router_discovery() failed to add default route" in my logs.
After a fresh reboot:

$ dmesg | grep "ICMPv6 RA: ndisc_router_discovery() failed to add default route." | wc -l
46

First, I thought this is a kernel issue, but than I found a bug-report in the Red Hat BTS in [1].

Just FYI: I am on Linux-3.4-rc4 - with the original Ubuntu/precise kernel I haven't seen this which is linux-image-3.2.0-23-generic (3.2.0-23.36).
