Hello. I've got problem with the newst ubuntu disribution Hardy Heron. It's based on kernel 2.6.24 (exactly 2.6.24-12-generic - x86). Ubuntu used to be a good choice for laptop but after seeing powertop result I'm thinking about distor change..
Please look at the results. It's an idle system with xorg running. Machine is T8300 based lenovo t61 with nvidia NVS 140M graphics card. Wifi is intel 4965 card with iwl 1.2.0 driver. Power usage was about 16W on older kernel, but now it is 22 up to 25W in idle. Additional abiility to get into C3 is closed to 0. Of course sometimes it works quite nice, but after some minutes it's ALWAYS getting wired. Do you noticed such a problem with this kernel? I've googled this issue many times but with no success.. It's also on ubuntu launchpad reported as a bug with 'in progress' state - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/177895 PowerTOP 1.9 (C) 2007 Intel Corporation Collecting data for 15 seconds Cn Avg residency C0 (cpu running) (46,5%) C1 0,0ms ( 0,0%) C2 0,0ms (49,7%) C3 0,0ms ( 3,8%) P-states (frequencies) 2,41 Ghz 0,7% 2,40 Ghz 0,0% 2,00 Ghz 0,0% 800 Mhz 99,3% Wakeups-from-idle per second : 40905,2 interval: 15,0s Power usage (ACPI estimate): 22,9W (1,6 hours) Top causes for wakeups: 92,9% (2641,7) <kernel IPI> : Rescheduling interrupts 1,9% ( 54,4) <interrupt> : acpi 1,7% ( 48,3) <interrupt> : extra timer interrupt 1,4% ( 40,3) opera : schedule_timeout (process_timeout) 0,7% ( 20,3) <interrupt> : iwl4965 0,4% ( 10,6) <interrupt> : ahci 0,3% ( 8,0) <kernel module> : usb_hcd_poll_rh_status (rh_timer_func) 0,1% ( 1,9) gnome-terminal : schedule_timeout (process_timeout) 0,1% ( 1,7) wpa_supplicant : schedule_timeout (process_timeout) 0,1% ( 1,5) <interrupt> : PS/2 keyboard/mouse/touchpad 0,0% ( 1,3) kcryptd : blk_plug_device (blk_unplug_timeout) 0,0% ( 1,1) <kernel IPI> : TLB shootdowns 0,0% ( 1,0) <interrupt> : uhci_hcd:usb5, yenta, nvidia 0,0% ( 1,0) Xorg : nv_start_rc_timer (nv_kern_rc_timer) 0,0% ( 1,0) dhcdbd : schedule_timeout (process_timeout) 0,0% ( 1,0) cpufreq-applet : schedule_timeout (process_timeout) 0,0% ( 1,0) nm-applet : schedule_timeout (process_timeout) 0,0% ( 0,9) NetworkManager : schedule_timeout (process_timeout) 0,0% ( 0,9) sensors-applet : schedule_timeout (process_timeout) 0,0% ( 0,6) pulseaudio : schedule_timeout (process_timeout) 0,0% ( 0,5) iwl4965 : ieee80211_sta_work (ieee80211_sta_timer) 0,0% ( 0,5) <interrupt> : eth0 0,0% ( 0,5) <kernel module> : neigh_table_init_no_netlink (neigh_periodic_timer) 0,0% ( 0,5) NetworkManager : e1000_intr_msi (e1000_watchdog) 0,0% ( 0,4) gnome-panel : schedule_timeout (process_timeout) 0,0% ( 0,4) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) 0,0% ( 0,3) syslogd : schedule_timeout (process_timeout) 0,0% ( 0,3) gnome-power-man : schedule_timeout (process_timeout) 0,0% ( 0,2) update-notifier : schedule_timeout (process_timeout) 0,0% ( 0,1) Xorg : do_setitimer (it_real_fn) 0,0% ( 0,1) sm-notify : do_journal_end (delayed_work_timer_fn) 0,0% ( 0,1) operapluginclea : schedule_timeout (process_timeout) 0,0% ( 0,1) metacity : schedule_timeout (process_timeout) 0,0% ( 0,1) Xorg : schedule_timeout (process_timeout) 0,0% ( 0,1) <kernel core> : page_writeback_init (wb_timer_fn) 0,0% ( 0,1) gnome-volume-ma : schedule_timeout (process_timeout) 0,0% ( 0,1) <kernel core> : end_that_request_last (laptop_timer_fn) 0,0% ( 0,1) iwl4965/0 : sta_info_start (sta_info_cleanup) 0,0% ( 0,1) <kernel core> : ndisc_dst_alloc (fib6_run_gc) 0,0% ( 0,1) Xorg : neigh_update (neigh_timer_handler) Regards, barteq _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
