Also the power consumption is a lot higher than with 2.6.24.5= =2E=20 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 previ= ous=20 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 see= m=20 to do anything for me. I have also tried 2.6.25-git3, but no changes.
