Subject: Netconsole crash on 2.6.38-rc3

I'm trying to debug an xHCI driver crash on 2.6.38-rc3, and netconsole
is crashing when I try to load it.  I will try to update to 2.6.38-rc5,
but I'm sort of stuck on rc3 since Greg KH's USB tree is based on that.

Attached is the two scripts I use to set up my box and call netconsole.
netconsole-on-network.sh is called first, followed by
netconsole-ending-on-network.sh.

When I invoked the netconsole-ending-on-network.sh script, netconsole
failed to load with an error about having the wrong ethernet device.  My
ethernet device apparently migrated from eth1 to eth0 on that box.

After modifying my script, unloading the netconsole driver, and
re-running netconsole-ending-on-network.sh, I got a "Killed" message
with the attached trace in dmesg.

Is this a known bug on 2.6.38-rc3?
