    I reported a problem with the AMD initialization just last week.
    There is an issue with amd_pmu_cpu_online() which gets called
    too early, and thus fails. That leaves some bogus state and causes
    a crash in amd_pmu_cpu_offline().

    I proposed a fix which was rejected. The alternative involves moving
    some the of CPU initialization code (on AMD) to an earlier position,i.e.,
    which would be executed before the CPU_STARTED notifier. Nobody
    has proposed anything else so far.
