Feel free to ask me for what else might be needed here.
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!
Cheers,
Don
