Thanks for the info. This is what I thought, the system has no lapic. I think I am going to re-arrange some code to properly deal with this scenario. Not having a lapic should not be a KERN_ERR, the nmi watchdog should just accept it, print out a quiet message and move on. :-) Thanks for finding this and providing the info!
