Comment 63 for bug 585765

Brand new Lenovo T510, 4gb RAM, Intel i5 (4 core) processor running Lucid. It's been freezing from day one. Just added pae to kernel (2.6.32-22-generic-pae) last week (for some reason installer did not see that I had 4gb of mem). Still, no difference, the computer is still freezing. The screensaver was running and I moved the mouse to wake it up and it froze. The good news is that I can SSH to it (usually it is completely hosed). Right TOP shows 99% cpu idle.

Attached is kern.log with what could be an interesting stack trace:

I have everything in /var/log/ If other logs would be useful then let me know.

Some other things to note: compiz is disabled, virtual box is disabled. When this current crash happened I was on AC power and I have the power settings set to not sleep, or spin down harddrives or anything, just turn on the screen saver (which is opengl picture show IIRC).
