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.
