[Bug 1813819] Re: The kernel speeds up and down unexpectedly

New update:
- When using arrow keys, the keyboard random spews out num key values of the arrows as if the button is stuck even when number lock is off. All I have to to replicate this bug is to hold arrow key down
- Putting the laptop into sleep and waking it up, seem to reduce the clock speed effect until it reboots again. (it made the computer usable enough for me to take the bug report and start pushing my files to repos)

Title:
The kernel speeds up and down unexpectedly

Status in linux package in Ubuntu:
Confirmed

Bug description:
It initially started while I was browsing and I noticed the page load idle logo was going a bit too fast. First I ignored it assuming I was wrong or it was not significant. So i decided to test the playback time in videos and the Linux clock and sure enough, everything is about 10% tp 20% faster. So I rebooted the OS to see if problem persists.it actually got worse Everytime I rebooted. The os starts up normally but as soon as I log in, everything gets faster and faster until keyboard, mouse become unusable. A gentle tap of the keyboard spams the screen with that letter. Then I rebooted again and as if it was some kind of overflow the os is now snail pace slow. When I tap a button it outputs a letter about 1 to 2 seconds after. The mouse moves at normal speed however.unfortunately the OS is unusable and I'm typing this bug report using a different device. Please let me know if there is a way for me to get logs remotely cause as it is OS is useless. I'll try too keep rebooting to see if there is a "usable" speed that I can get logs and upload. Hopefully by the time this bug is processed I'll get the report. In the mean time please feel free to ask me anything that would help you pin point the issue.
