Inaccurate
Description
The IBS Op Data 2 Register[NbIbsReqDstProc] (MSRC001_1036[4]) may be incorrect when the

Sampling (IBS) is executed and IBS Op Data 2 Register[NbIbsReqSrc] (MSRC001_1036[2:0]) is
011b or 111b. This typically would not result in a statistically significant number of incorrect
samples.
