Since upgrading to Fedora 18, the power consumption has been super high, battery life very short, fans running always, temperature very high, mouse laggy etc. The problem is sever enough that the system is only barely usable. The high drain seems to start upon logging into the desktop environment (cinnamon). I did not have this problem in Fedora 16. This video driver is i915.

Created attachment 698422 [details] Ouput of 'powertop --html' when running with kernel-3.7.7-201.fc18.x86_64
Created attachment 698423 [details] Output of 'powertop -html' on F16 where problem does not occur, for comparison.
Created attachment 698424 [details] Output of 'powertop --html' when running with kernel-3.7.7-201.fc18.x86_64 after things spontaneously came good. Note that the problem occasionally apparently spontaneously goes away. Here is an example of what powertop output looks like after this has happened.
It's certainly possible this is related to 866212. Adam, should we dup?
Maybe it is not a dup. I had power issues with this kernel and some older ones too, but not with kernels older than 3.7 as mentioned in 866212. BTW: everything is working fine on my machine with 3.7.8-202.fc18.x86_64 which has just been released.
This has been behaving much better lately, but I've just run into it again. kernel-3.7.9-201.fc18.x86_64 From powertop: Summary: 741.7 wakeups/second, 115.5 GPU ops/seconds, 0.0 VFS ops/sec and 103.3 Usage Events/s Category Description 399.5 ms/s 3.0 kWork output_poll_execute 154.1 ms/s 6.8 Process [kworker/0:1] 135.9 ms/s 18.1 kWork i915_hotplug_work_func 100.0% Device Audio codec hwC0D0: IDT 100.0% Device Audio codec hwC0D3: Intel 100.0% Device Display backlight 56.6 ms/s 9.4 Process [kworker/1:0] 0.2 pkts/s Device Network interface: eth0 ( 48.0 ms/s 5.3 Process [kworker/2:1] 45.0 ms/s 60.9 Process /usr/lib64/firefox/firefo 43.4 ms/s 56.4 Process /usr/bin/cinnamon 37.5 ms/s 21.4 Process /usr/bin/Xorg :0 -backgro 100.0% Device Radio device: btusb 19.1 ms/s 112.8 Process roxterm I am running the cinnamon DE, and I only had roxterm and firefox open when I ran into this again. I had been browsing the web for a while, and then the mouse lag kicked in, the fans cranked and I saw the above in powertop. According to the changelog, there was another i915 change in the last kernel update, so I'll try dropping back to the previous version. It's tricky to say when it's gone though, since it can appear spontaneously after using the computer for a while.
I tried (soft) rebooting into kernel-3.7.8-202.fc18.x86_64 and kernel-3.7.7-201.fc18.x86_64 and the high CPU/extreme mouse lag was still present from login. In fact the keyboard response in the grub boot menu was even very laggy. Powering the machine off and on again made the problem go away (thanks, IT crowd!), even booting back into kernel-3.7.9-201.fc18.x86_64. Note that when I booted in kernel-3.7.8-202.fc18.x86_64 and kernel-3.7.7-201.fc18.x86_64, abrt notified my that they had kernel oopses: "irq 16: nobody cared (try booting with the "irqpoll" option)".
Still a problem on kernel-3.7.9-205.fc18.x86_64.
kernel-3.8.1-201.fc18.x86_64 still happens, e.g. after a few hours of fairly pedestrian web browsing: Summary: 657.5 wakeups/second, 143.4 GPU ops/seconds, 0.0 VFS ops/sec and 81.9% Usage Events/s Category Description 539.3 ms/s 61.0 kWork i915_hotplug_work_func 171.9 ms/s 21.2 Process [kworker/u:0] 100.0% Device Audio codec hwC0D0: IDT 100.0% Device Audio codec hwC0D3: Intel 100.0% Device Display backlight 40.6 ms/s 170.0 Process /usr/lib64/firefox/firefo 23.3 ms/s 19.1 Process /usr/bin/Xorg :0 -backgro
FWIW, I haven't seen this happen on later 3.8.x kernels, so perhaps it has been fixed. The fan does still run continuously on one system though (HP 6710b Core 2 Duo GMA X3100), which wasn't the case in the past.
I am seeing this problem on my new Dell XPS 13 (that's the latest Project Sputnik laptop, so Ubuntu is running OK on this machine) also under Cinnamon. (Gnome 3 is not quite as bad, but has also unreasonably large CPU time for Xorg and Gnome Shell). I attach a screenshot which shows that a single instance of system-monitor gets the system to approximately 200% CPU load! I will also attach my dmesg output in case this is useful. Today I installed Fedora 19 prerelease, and it is completely fine. CPU load close to zero in idle. Since the prerelease also fixes suspend/resume on the XPS 13, I am staying with prerelease for now (it feels much more stable and mature than F18 on this machine...) But if it helps fix anything, I could run some tests on F18 if necessary.
Created attachment 750150 [details] Screenshot showing unresonable CPU load on system-monitor CPU load fluctuates, this shot is on the low end of what is actually seen.
Created attachment 750151 [details] my dmsg output
This is happening in my 3rd Gen core i7 laptop with a significant high CPU temp and fans spinning wild while using firefox. Arch linux behaves a lot better. Happens in both Fedora 20 Beta and fedora rawhide.
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
