No Joshua, exactly 'nmi_watchdog=1' since it's important to find who is responsible that cpu is stuck while testing nmi watchdog. 'debug and apic=debug' will show additional info what is happening. And it would be just great if you able to try latest -tip/master http://people.redhat.com/mingo/tip.git/README since there a lot of work/fix are done. If it's a problem to fetch this kernel thru git - me or Ingo (I suppose) could make tar.bz2 archive so you'll not need to fetch the whole history. I wouldn't say I'm really specialist in this area so your report could be quite important not for me only but for others too. - Cyrill -
