Hi swmike, You mentioned you tested an upstream 2.6.27 kernel from kernel.org. Since this is the case this should really be escalated to the upstream kernel developers in a bugzilla.kernel.org report. Care to file this there as well? We can then link this bug report to the upstream one. For more information please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies#Reporting Bugs Upstream .

[Bug 263260] Re: ipv6 stops working after a while
I have now tried kernel.org latest kernels of 2.6.25, 2.6.26 and 2.6.27 and they all have the same problem, I also booted a harlddy installation with my kernel.org 2.6.26.3, and it had the same problem also. The weird thing is that I had ipv6 working perfectly with my old hardy installation (hard drive broke so I had to re-install). I'm at loss as to what is going on here... No configuration has changed on the cisco router and it's running a very recent IOS so there should be no problem there either. I have disabled IGMP snooping on my switch, didn't change anything either. -- ipv6 stops working after a while https://bugs.launchpad.net/bugs/263260 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have created a cron script that is run every hour, that pings an ipv6 address.

Hi swmike, You commented that you had no issues with a custom compiled 2.6.26.3 kernel. I'm curious if you were ever able to test a 2.6.26 Ubuntu kernel from Intrepid? The reason I ask is I'm wanting to know if this is specifically a regression with the new 2.6.27 Ubuntu kernel of if it existed also with the 2.6.26 Ubuntu kernel. I know the Alpha4 releases of Intrepid contained a 2.6.26 kernel - http://www.ubuntu.com/testing if you'd be interested in testing.
