AMD A10-7850K APU with Radeon(TM) R7 Graphics, Linux 4.18.7-rt5 (Profile)

Latency plot of system in rack #2, slot #7
Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by SMIs
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes
Characteristics of the alll highest latencies:
