I'm not sure what's needed to bisect the kernel? What would I need to
do?

Title:
CPU frequency stuck at minimum value..again Ub
The speed is limited on every boot now...I also notice my bios time
being reset to 2013...when unplugged from the wall (I'm going to open it
up, the cmos battery may have died.)

Now after another reboot the speed is stuck at 800mhz again and doesn't

Yes I can get it to boot into active mode thanks to Doug, but after
several minutes the cpu drops to 798-800mhz and won't increase no matter
if I try and change it. I did notice that the scaling_governor always
boots to powersave mode. When I change it to performance after several
minutes the cpu
Here's a list I can't remember the last time it worked, if you do a
google search on "ubuntu cpu lowest freq" seems to be a very common
problem but none of the fixes work for me.
I can't change the speed of my CPU's in my bios (a system76 linux machine).
What do you want me to check in the bi
