Am running with the 22-rc4-mm2-hrt4 patch on my Latitude D820. Mostly seems to work, but for some reason the Intel 'powertop' util thinks it's 100% busy: PowerTOP version 1.7 (C) 2007 Intel Corporation Cn Avg residency (5s) P-states (frequencies) C0 (cpu running) (100.0%) C1 0.0ms ( 0.0%) 2.00 Ghz 0.0% C2 0.0ms ( 0.0%) 1.67 Ghz 0.0% C3 0.0ms ( 0.0%) 1333 Mhz 0.0% 1000 Mhz 100.0% In reality: [/sys/devices/system/cpu/cpu0/cpuidle] for i in */*; do echo -n "$i: "; cat $i; done state0/latency: 1 state0/power: 1000 state0/time: 0 state0/usage: 3 state1/latency: 1 state1/power: 500 state1/time: 1756017623 state1/usage: 1837402 state2/latency: 57 state2/power: 100 state2/time: -159524787 state2/usage: 15007443 I think we have a 32/64 bit issue on state2/time which is probably borking things up....
