Public bug reported:
My temperature rapidly increases from 38C to 65C if I leave a properties
dialog open. CPU usage is close to 100%, but oscillates.
Even stranger, the temp still spikes when I'm in powersave mode. No
other application I have ever used causes the temperature to get this
hot
Specifically it happens in the properties for a UML class object, would
have to test to see which properties dialog causes this problem.

Title:
Ah, thanks for the info. That's consistent with the bug that syncing
causes the freezes.
I haven't had a freeze since switching to Firefox. Thanks everyone for
your help and suggestions.

Got another hardlock even with Chromium. Switching to Firefox, will
report if it freezes.
If someone else could comment if they've seen these with Ubuntu 11.10,
Chrome/Chromium that would be great.

Did you have sync setup on Chromium? The link I posted above says it
only happens when it syncs in the background. Also, how much do you use
Firefox vs. Chromium? Obviously if you don't have Chromium open much it
probably wouldn't happen.
Thanks for the info,
Charles

This is quite surprising to me, but I switched to Chromium from Chrome and I
haven't seen a hardlock since my last post. This comment on Google's help
section confirms this as a possibility:

This thread also reports
Garry: so maybe Chromium + 11.04 = hardlocks, but Chromium + 11.10 = no
hardlocks.
If I get a hardlock with Chromium I'll report it here and switch to
firefox :-)

Dag: I switched to xfce and rox-filer shell / file manager and it
happened again, immediately after resuming from suspend. So we can rule
out Unity as the issue.
I'm not sure how to use lshw, looks like I have to do sudo lshw
some_text_file prior to the crash? Here are the other outputs.
lspci
Dag: Interesting, we both have the Intel Centrino UItimate-N wifi
module. That wasn't the default--I ordered mine through lenovo directly.
I wonder if it's hard-locking when it tries to connect to an AP?
dmesg appears to flush every time I reboot. What's a good way to get
general hardware
OK lshw was just incredibly slow to run, perhaps while my wifi was
connecting. Here's the output with -short:

Dag Rende: What shell are you running? Gnome3 or Unity?
If you're not having issues with T420s, maybe it's due to my SSD,
bluetooth, or getting an Intel Wifi module instead of the default
thinkpad one.
Which of the T420s models did you get?
To add another example. I also experience hardlocks with my Sandybridge
T420. Keyboard input and mouse input is unresponsive, all applications
stop updating.
This problem happens seemingly randomly, though it appears to happen
more immediately after resuming from suspend. A hardlock ALWAYS occurs
To add to my above comment, I'm running 11.10 and this has NOT fixed the
problem. To those that don't have the problem in 11.10: do you have
Sandy Bridge or another graphics card?
Are you running x64 as I am?
