Whenever ipv6 is enabled in 2.1.x, I get the following oops after a couple of
minutes max. After the oops, /proc/net/dev is corrupted. Sometimes it is still
readable afterwards, but interfaces eth0 eth0:0 ippp0 ippp1 and ippp2 are gone.
Any program which accesses an interface hangs, and doesn't respond to signals.
This has been happening since very early in the 2.1.x tree.. reported once.
Myopic one (moi) isn't making a lot (~0) of progress toward fixing this.
