Description Robert Frohl 2022-02-10 12:45:56 UTC 
rh#2049528

Under complex microarchitectural conditions, an unexpected code breakpoint may cause a system hang. The hang has been observed on a Skylake server processor, subsequent analysis indicated additional potentially affected processors. The potential exists for a Temporary Denial of of Service (TDOS).
