I just reinstalled a fresh 12.04 because I couldn't even get booted on my previous installation anymore.

I just installed 8GB of ram on this laptop, but the problem happened even before this, and all I have installed in this run on Ubuntu is: ia32libs, Oracle JDK7 and the 32bit JRE junipernc jupiter

The laptop has never been used very heavily, so could someone get back to me on this, let me know what further information you need about my machine, or files to upload. Thanks!

If it helps I do see this entry when i grep 'fail' in my kern.log: [drm] MTRR allocation failed. Graphics performance may suffer. and: init: failsafe main process (791) killed by TERM signal – Kris Jun 17 '12 at 2:09

Check if your random system lookups happen during file operations, if they do you might try using another scheduler for example : echo "deadline" | sudo tee /sys/block/sda/queue/scheduler

If it does here you can find out how to make it permanent.

If you could summarize the important information on that page in your own words your answer (by editing your answer), while continuing to provide the link for reference, that would make this answer even better. – Eliah Kagan Jun 30 '12 at 12:26
