Trouble with 2.6.11 Linux

Hello,
	
I have a 2.6.5 Linux running router radvd.
I also have 2.6.5 clients(and a 2.4.20 client) that accept the router
advertisements from the router and acquire a Link-Global address and also
autoconfigures their Link-Local address. 
Their configs:
ipv6.conf.eth0.accept_ra=1
ipv6.conf.all.accept_ra=1
ipv6.conf.default.accept_ra=1

I have a 2.6.11 client host that does not accept any router advertisements
even though it's config is the same as above. (I have compared the "sysctl
-a" output on both the 2.6.5 and 2.6.11 and they are identical).  In fact
the following is what occurs at boot time:

1.  When I boot up this client, eth0 does not have the inet6 Link-local
address.
If I then issue:
ifconfig eth0 down
ifconfig eth0 up

The inet6 Link-local address then appears.

2. My 2.6.11 host does not learn this prefix and as a result there is no
Link-Global address.

Has anyone experienced this issue.

Thank you,
Phil Bellino
