if you have got the sandy bridge processor, do NOT give into increased-graphics-performance temptation and upgrade to the 3.1 kernel.

There is a 76% power regression vs 2.6.3x kernels http://www.phoronix.com/scan.php?page=article&item=linux...

You can always download and install the latest kernels while keeping the older versions as backup. No need to worry about GRUB settings either as that's all handled when you install the kernel debian packages.

Only caveat to this is you might have to reinstall your graphics driver for the new kernel.

Thanks for the info. This does affect me. I'll be sticking to 2.6.38 until they sort these issues out.
