Geekbench has detected a 27.3s difference between the clock (229s) and the high-resolution timer (202s) on your system. Since this difference can affect benchmark results, Geekbench will not display the benchmark results.

But:

$ cat /proc/cmdline 
BOOT_IMAGE=/vmlinuz-4.8.0-41-generic root=/dev/mapper/vg00-lv_root ro priority=low clocksource=hpet hpet=force


$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource hpet


$ cat /sys/devices/system/clocksource/clocksource0/available_clocksource tsc hpet acpi_pm

Previously in this system installed Phenome II x4 965T, and used default clocksource tsc - but geekbench not detect differences.
Currently with FX-8320E Geekbench detect differences with clocksource tsc and if clocksource force switched to hpet.
And I tryed disable hpet (and/or tsc) in BIOS and in kernel on load - but Geekbench still detect difference between the clock and the high-resolution timer.

I think in Geekbench using wrong method for detect difference of clock under linux.

Also Geekbench wrong detect cores and threads for FX-8320E:

  Processor               AMD FX-8320E @ 3.20 GHz
                          1 Processor, 4 Cores, 8 Threads
This cpu have not threads, it have 8 real cores.

    Two years later, same wrong detection AMD CPU cores, this CPU have 8 cores, not 4 cores:

    21:13 $ ./geekbench4
