Recently I’ve been experiencing some system instability in my desktop. Windows seemed to work fine, but whenever I booted into Ubuntu my system would pause periodically.

At first I thought this had to do with my pretty bootleg / manual install of wireless drivers, so I uninstalled them. Then I wondered if my cooling wasn’t doing a good job and maybe it was a processor pause. But that didn’t seem to add up because Windows didn’t have issues.

I started wondering if my linux drive was bad (my windows and linux partitions are installed on separate drives) so I decided to do what I should have done earlier and check dmesg. Bingo! Turns out there were these funky errors:

I googled this and turns out it means either my SATA connectors are bad or I’m using a bad SATA cable. Cool. Replacing them and will see if it solves the problem.
