Public bug reported:

IBS is a code profiling mechanism that enables the processor to select a random instruction fetch or micro-op 
after a programmed time interval has expired and record specific performance information about the operation. 
An interrupt is generated when the operation is complete as specified by MSRC001_103A [IBS Control]. An 
interrupt handler can then read the performance information thatwas logged for the operation
