Frequent total system freezes on T60 since upgrade to Hardy

[Poilar]

Since I upgraded to Hardy, I've been experiencing frequent total system freezes. At this point only my mute and unmute buttons appears to work and I have to hard boot my computer in order to restart. There appears to be no errors reported in my syslog.

Just so you know, I use a Thinkpad T60 that previously worked perfectly on Gutsy (never had freezes before).

These freezes tend to happen when I don't touch the computer for a while (e.g. when I'm watching a movie fullscreen or when I go away and the screensaver is on). However, they don't occur 100% of the time when I'm away (e.g. two nights ago my computer still was working when I woke, but this morning it was frozen).

Ideas?

Update: Since I switched my screensaver from a blank screen to something active, I no longer get freezes overnight. However, my computer still does periodically freeze when watching a video fullscreen.

Any log files to share? I'm assuming at that point you have to do a power cycle and reboot. I don't know what's inside a Thinkpad T60. Maybe a little rundown on video, cpu, and things. How about 'fdisk' output...okay I see no syslog errors. Does 'dmegs' give up anything?

I don't believe there are any errors in dmesg, though I'm a little less clear as to what exactly dmesg contains. This creates a new file each boot, right? So, I need to look at dmesg.0 to see what happened before it crashed? There's nothing unusual at the end of the file.

Below are some maybe relevant outputs:

fdisk output is as follows:

Here's the output of lshw -short so you can see my hardware:

I read someone had freezes while on battery , another while using multi-bay.
Your running on AC when this happens, correct?

[Poilar]

Yeah, running on AC when this happens.
