Eric Northup 54a20552e1 KVM: x86: work around infinite loop in microcode when #AC is delivered ... It was found that a guest can DoS a host by triggering an infinite stream of "alignment check" (#AC) exceptions. This causes the microcode to enter an infinite loop where the core never receives another interrupt. The host kernel panics pretty quickly due to the effects (CVE-2015-5307).
