No, it boot and work normally. The only thing i bother, is the additional 260 timer interrupts per seconds. Here is short result: c1e enabled: -- power consumption about 23 watts -- there is only C1 power state enabled -- there are about 260 timer interrupts per seconds tested with x86_64(2.6.22, 2.6.23-rc8, 2.6.23-rc8-hrt1 ), i386(2.6.21, 2.6.22, 2.6.23-rc5-hrt1) c1e disabled: -- power consumption about 27 watts -- there are no any power state enabled (including C1) -- there are no additional 260 timer interrupts per seconds tested with 2.6.23-rc6-hrt1/x86_64. I want to reduce the power consumption of my notebook. I see the 2 possibility: -- remove 260 additional timer interrupts (c1e enabled case ) -- force enable C1, C2 and C3 states (c1e disabled case) Do you have any idea how it can be reached?
