A better test with that kernel is to disable HT in the BIOS and then boot. note that there is a fix in tip for this, as mentioned in the bug report: https://bugzilla.kernel.org/show_bug.cgi?id=5471 WRT intel_idle vs acpi_idle, the best way to compare the two is with CONFIG_INTEL_IDLE=y and boot with and without intel_idle.max_cstate=0 which disables intel_idle (and thus enables acpi_idle). Re: 2.6.35 taking more power overall. See if the wireless state has changed vs previous. the powertop2 should help track down this kind of thing when it becomes available. thanks, Len Brown, Intel Open Source Technology Center _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
