(Get the code!)
Ubuntu Maverick (up-to-date with latest packages as of 19:25 GMT September 20th)
Essentially, unless the keyboard or mouse is constantly in use, the system freezes/locks up/appears to be doing nothing. As soon as the keyboard is pressed or the mouse is moved, everything starts going again.
Examples:
* System will never make it through boot process unless ctrl (or other) key is held down, just hangs
* I'm watching a video, if I don't hold down a key, press a key every few seconds or constantly move the mouse, then it will stop playing and the sound will loop, playback resumes as normal as soon as I trigger an input again
* I'm running aptitude update, if I don't keep moving the mouse or whatever, it will appear to stop doing anything (get stuck). I can't tell whether it is doing nothing or just appearing to do nothing. Again, as soon as I trigger an input again, everything starts back up (for a few seconds and then it stops again, unless I keep triggering inputs)
* I'm shutting down, it won't ever get there unless I keep pressing/hold down keys, it will just hang. I've left it all night and in the morning it's still stuck at the same point. Hold down a key and off it goes again.
It affects everything, not just these things. These are just some of the best examples. Freeze ups are not localised to one window, seems to affect everything. I can't be sure, but I reckon it is probably doing something funny with the hard disk when on battery mode (seems to be spinning up and down more often). Hard disk partitions are all ext4, both have plenty of free space.
It seems to have been a problem since I upgraded to Maverick a week or two ago. But in the last day it has become more severe. Previously, it only seemed to affect boot up and down, not it is affecting normal desktop usage (like videos). May coincide with a recent update to 2.6.35-22 from 2.6.35-x. I have booted into 2.6.32-x instead and the problem does not exist at all there. Definitely did not exist in Lucid either. Definitely looks like a kernel issue based on that.
Hardware is Lenovo Ideapad S12 with Intel Atom processor and Intel graphics.
This a big problem for me. It is making my computer almost unusable. Please could someone look into this urgently.
