Thank you Len, I do appreciate your interest to my issue. The kernel 2.6.26 and all below are working perfectly fine, as you said: "out of the box" without any command-line workarounds:) And starting from 2.6.27 and ALL kernels above are on this issue. So it is really looks as a regression. As per your request I booted 2.6.26.8 and here are the outputs that you're interesting: r...@dmitry:/home/dima/work/bug1# cat /proc/acpi/processor/*/power active state: C0 max_cstate: C8 bus master activity: 00000000 maximum allowed latency: 3000 usec states: C1: type[C1] promotion[--] demotion[--] latency[000] usage[00172803] duration[00000000000000000000] C2: type[C2] promotion[--] demotion[--] latency[005] usage[00000000] duration[00000000000000000000] C3: type[C3] promotion[--] demotion[--] latency[020] usage[00000000] duration[00000000000000000000] active state: C0 max_cstate: C8 bus master activity: 00000000 maximum allowed latency: 3000 usec states: C1: type[C1] promotion[--] demotion[--] latency[000] usage[00142512] duration[00000000000000000000] C2: type[C2] promotion[--] demotion[--] latency[005] usage[00000000] duration[00000000000000000000] C3: type[C3] promotion[--] demotion[--] latency[020] usage[00000000] duration[00000000000000000000] r...@dmitry:/home/dima/work/bug1# grep . /sys/devices/system/clocksource/*/* /sys/devices/system/clocksource/clocksource0/available_clocksource:hpet acpi_pm jiffies tsc /sys/devices/system/clocksource/clocksource0/current_clocksource:hpet Also kindly see attached output of dmesg -s 64000 Please let me know if any other info I can provide.
