According to Intel 64 and IA-32 Architectures SDM, Volume 3, Chapter 14.2, "Software needs to exercise care to avoid delays between the two RDMSRs (for example interrupts)". So, disable interrupts during reading MSRs IA32_APERF and IA32_MPERF. See also: commit 4ab60c3f32c7 (cpufreq: intel_pstate: Disable interrupts during MSRs reading).
