iwl3945 and power saving

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I finally upgraded from 2.6.30 to 2.6.33 (mostly for TRIM support) on my
laptop and find that power saving doesn't seem to work any more on its
iwl3945 card.

The extra power consumption is quite significant, so I'm considering
compiling my own driver, manually re-enabling the power-saving code.

But before I do that, I'd like to know what is the risk involved (it
seems pretty serious since it warranted removing the feature
altogether, even tho it was runtime-disabled by default anyway).
