fixed 649540 3.1.5-1
thanks
This issue appears to be worked around by
linux-image-3.1.0-1-amd64 3.1.5-1
Note that it is *not* fixed by
linux-image-3.2.0-rc4-amd64 3.2~rc4-1~experimental.1
The result is that idle time on battery *doubled*. I'm now getting
4 hours idle time on the small (3 cell) battery, which is what I was
expecting when I bought this laptop.
In case you're interested in what's going on under the hood -- the
kernel is now able to put the processor in one of the low-power
"package" states. Previously, the cores were able to switch to
low-power states, but the package remained in PC0.
