With the stable 2.6.25 release I still get a _massive_ amount of wakeups (around 50k). Also the power consumption is a lot higher than with 2.6.24.5. I am using a Mobile AMD Sempron (32bit) on an nx6125 laptop (Gentoo). In 2.6.25 an "extra timer interrupt" appeared, which was not there in previous kernel versions.
Power usage: 2.6.24.5: ~12-15 W 2.6.25: ~16-22 W
Wakeups: 2.6.24.5: 10-300 2.6.25: 900-50000!!
I thought the patch posted went into the stable kernel, but it does not seem to do anything for me. I have also tried 2.6.25-git3, but no changes.
Here are some links to potentially useful files (idle, no WLAN): dmesg-2.6.25: http://pastebin.ca/995545 powertop 2.6.25: http://pastebin.ca/995548 dmesg-2.6.24.5: http://pastebin.ca/995549 powertop 2.6.24.5: http://pastebin.ca/995550
If there is anything I can provide you with for debugging let me know.
