ok, it's indeed pretty conclusive:

| 2 CPUs, running 2 parallel test-tasks.
| checking for time-warps via:
| - read time stamp counter (RDTSC) instruction (cycle resolution)
|
| | TSC: 0.32us, fail:0 |

i suspect you ran it for at least a couple of minutes, and the ksoftirqd
anomaly occured during it, right?
