Anyway I have it fuzzing current git and surprisingly while it's hit a few WARNINGs and some NMI dazed+confused messages it hasn't actually crashed yet. Not sure if I want to let it fuzz overnight if I'm not here though. Shame on Intel though for not providing perf JSON files for the Pentium 4 event names. Vince
