Meh.. my machine keeps locking up with 15-rc1 and your fuzzer. It looks to get stuck a finish_task_switch() from a preemption while waiting for a perf IPI. Which is complete crack because we have preemption disabled over issueing and waiting for the IPI :/ I tried reverting some of the IPI related patches, but no joy so far, I'm about to go try a git-bisect on this. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
