Bug Description

On the ASRock E350M1 the test below fails.

```
FAILED [MEDIUM] MSRCPUsInconsistent: Test 1, MSR 0x00000175 SYSENTER_ESP has 1
inconsistent values across 2 CPUs (shift: 0 mask: 0xffffffffffffffff).
MSR CPU 0 -> 0xf77d0ab0 vs CPU 1 -> 0xf77e2ab0
```

According to Rudolf Marek, the test is incorrect.

Should the test be removed?
