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 -- Ben Greear Candela Technologies Inc http://www.candelatech.com
