I checked the init call which is calling synchronize_rcu(): subsys_initcall(pm_sysrq_init); this is being called after early_initcall. The order of initcalls is early, core, postcore, arch, subsys, fs, device, late. So I guess that is ok. I wonder why it was not showing up in 12.04. I have a dual boot. Will test it out and see if I can find something. -- Pranith -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
