This should be a cpufreq bug and reassign to the correct category. Could you
try intel_pstate driver?
Please provide the output of acpidump. Thanks.

Change kernel config file
set CONFIG_X86_INTEL_PSTATE
unset CONFIG_X86_ACPI_CPUFREQ

Created an attachment (id=105021)
--> (https://bugzilla.kernel.org/attachment.cgi?id=105021)
grep . /sys/devices/system/cpu/cpu*/cpufreq/* (CONFIG_X86_INTEL_PSTATE)
Seeing similar behaviour after compiling with CONFIG_X86_INTEL_PSTATE enabled,
except when problem occurs CPU speed will go as high as 897000 and when problem
cleared with s2ram as high as 3381000.
Also, many more values are seen in between these, whereas with
CONFIG_X86_ACPI_CPUFREQ the speed is mostly (maybe even always) either 800000
or 3200000.

Could you provide what powertop and htop show during CPU cores are stuck at
800Mhz.?
(including these powertop's tabs, Overview Idle stats Frequency stats,
Device stats, Tunables).

Do you need me to provide any more information? (Bug is still tagged with
"NEEDINFO".)
I have now disabled SpeedStep in the BIOS and the problem went away.

Sorry for later response. This seems a Bios issue. Is there newer Bios verison.

This bug is a Bios issue and can't resolve in the kernel. So close it.
