Public bug reported:
Sometimes the system is very slow, in terms of how fast applications
work. After I reboot, maybe a few times, the system returns to a normal
state. There are no background activities that affect the booting
process or after. The settings in BIOS are to default.
Note that this is happening only in Ubuntu and Linux Mint. On Ubuntu the
process is noticeable slow, even dragging a terminal window is slow.
Linux Mint is faster, although starting a CPU benchmark will quickly
show the slowness.
Windows 10 does not have any issues.
I suspect that it remains at 800 MHz.
