This goes back to 3.0 (and probably before that). It's fixed with this commit: 71babb2705e2203a64c27ede13ae3508a0d2c16c "tracing: change CPU ring buffer state from tracing_cpumask" Which looks to have made it into 3.5-rc1. Can you apply this to all the stable trees from 3.0 and beyond. Thanks, -- Steve
