Subject: repeatable 2.6.39-rc6+ lockup on Via C3 system

I have a reproducible lockup on a Via C3 board (with kernel compiled for C3).

This kernel has some wireless patches and the slub fix from a few days ago.

Same kernel (compiled for P-II, SMP, pre-empt) works fine on an Atom system.

Shortly after the login prompt I see this on serial console:

BUG: spinlock lockup on CPU#0, net.hotplug/1899, f5a2c470

I tried enabling lockdep and saw no splats.

I'm not sure why there isn't more of a backtrace...

Thanks,
Ben
