Package: linux-2.6 Version: 2.6.33-1~experimental.4 Severity: normal I recently switched to the new 2.6.33 kernel because of its support for the TRIM command for my SSD disk, but it turns out that it has one very serious regression: its iwl3945 driver seems not to provide any power-saving any more. This makes a significant difference on the overall battery-autonomy of my laptop.

This makes a significant difference on the overall > battery-autonomy of my laptop. This is an intentional change. The developers found that dynamic power saving is buggy on this hardware.
