Interfaces fail to autoconfigure IPV6 global address with 2.6.28-11 kernel

[Manuel McLure]

After upgrading from Intrepid to Jaunty Beta, interfaces no longer get an auto configured IPV6 global address:

eth0 Link encap:Ethernet HWaddr 00:1d:7d:a8:ee:22
          inet addr:10.128.1.2 Bcast:10.128.1.255 Mask:255.255.255.0
          inet6 addr: fe80::21d:7dff:fea8:ee22/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
          RX packets:22434 errors:0 dropped:0 overruns:0 frame:0
          TX packets:22801 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:10662818 (10.6 MB) TX bytes:2622283 (2.6 MB)
          Interrupt:251 Base address:0xe000

 If I reboot the same system using the 2.6.27-14 kernel from Intrepid the address does appear:

eth0 Link encap:Ethernet HWaddr 00:1d:7d:a8:ee:22
          inet addr:10.128.1.2 Bcast:10.128.1.255 Mask:255.255.255.0
          inet6 addr: 2001:470:1f05:257:21d:7dff:fea8:ee22/64 Scope:Global

          Interrupt:251 Base address:0xe000

Doing tcpdump on the server running radvd shows that there are no autoconfiguration requests being recieved from the system booting with 2.6.28-11 kernel.

A bit more information. This seems to be a problem with the 64-bit version of the kernel, but on my 32-bit laptop which I just upgraded to 9.04 it seems to work fine.

I experimented some more, and found that the 64 bit livecd did get the IP, so I did a fresh install and this seems to work. It was something to do with my old many times upgraded installation. This bug should be closed.
