Description Per Steinar Iversen 2007-01-19 04:45:41 EST
Description of problem:

kernel-2.6.19-1.2895.fc6.x86_64 does not autoconfigure IPv6 at boot.
kernel-2.6.18-1.2869.fc6.x86_64 works ok.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Install kernel-2.6.19-1.2895.fc6.x86_64
2. Boot
Actual results:

No public IPv6 address found on eth0. The link-local one is present (fe80::...)

Expected results:

A public IPv6 address should be active on eth0

Additional info:

Running kernel-2.6.18-1.2869.fc6.x86_64 seems to be the best current workaround.

I've seen this as well - the router discoery message seems to be sent, and radvd
seems to reply with a router advertisment message but it seems tobe ignored and
no address is allocated.
Comment 2 Eric Hopper 2007-01-20 15:02:06 EST
I'm also having this exact same problem.
Comment 3 Pierre Ossman 2007-01-21 06:45:18 EST
Apparently a fix in (which I assumed has been merged into RH:s kernel)
broke this. The fix has been posted to netdev:


It would be nice if this could be included into the RPM in the near future.
Comment 4 Eric Hopper 2007-01-23 05:59:26 EST
Can the severity of this be changed to high?  It should be at least 'high'
because this completely breaks almost any IPv6 LAN with FC 6 boxes on it.
Comment 5 Peter Bieringer 2007-02-09 06:59:42 EST
Same problem hits me on an i686 kernel, not nice...
Comment 6 Chuck Ebbert 2007-02-09 09:42:57 EST
Fixed in pending update kernel, built yesterday, should go into testing today.

Comment 9 Per Steinar Iversen 2007-02-13 10:02:08 EST
Today kernel-2.6.19-1.2911.fc6.x86_64 appeared on updates-testing. It fixes the
problem on my machine at least.
Comment 10 Andreas Müller 2007-02-14 05:09:33 EST
2911 fixes the problem on two i686 machines.
Comment 11 Eric Hopper 2007-02-15 14:14:42 EST
It works for me on my dual processor 2.6.19-1.2911.fc6 system.

25 days lag between noticing a problem with the IPv6 equivalent of DHCP and
having it fixed seems a little ridiculous to me.  Should I simply not bother
with IPv6 on any of my networks since RedHat doesn't really want to support it?
