Thanks Dave, I was kind of suprised too, but we definately weren't recording the
rxhash. FWIW It doesn't appear to be a regression. I can't find where in the
history we ever had the hooks. Perhaps at one point tcp and udp rcv paths were
common between ipv4 and 6 address families, and then we bifurcated without
replicating the sock_rps_save_rxhash calls?

I can't seem to clone the repo, although I can see source on gitweb.
$ git clone git://git.linux-ipv6.org/gitroot/iputils.git
Cloning into iputils...

Is something amiss?

NCCI TTY device nodes. User space (pppdcapiplugin) works without
noticing the difference.

Ughh. I deleted a line of text from the e-mail I sent. I found my

The below code is from arch/mips/<myboard>/platform.c.
Perhaps this is vague, so I'll clarify. I start this process from the
board level configuration, therefore the mdio class (which gets created
in the init of mdiobus) isn't -- thus class->p is empty.
So, now I just need to relocate this code to some "real" network driver,
I guess.

Thanks for the replies,
Yes indeed, I bet that conntrack was the item that caused the grief I saw.
In fact turning off CONFIG_NETFILTER disables conntrack and solved my
problem. :-)
Now the question is how to get the netfiltery/conntracky goodness without
impacting those who want to go fast, maybe without a helmet.

Thats pretty simple, just load netfilter modules if necessary.
If not loaded, cost is pretty small, being predicted branches.

A bisect points at commit 04f482faf50535229a5a5c8d629cf963899f857c for the
first bad one. Unfortunately, I have not made netconsole work yet and the
hang is happening mostly right when X starts so I can't even see the console.
I will keep at the netconsole and see if I can get it functioning, also I will
try to boot this kernel in a VM and see if that helps.
