[SOLVED] 20,000 acpi interrupts showing in powertop

Hello,
I have been trying to track down the reason my system runs a little hot, and
when running powertop, I noticed that there were (what seemed like) a ton of
interrupts from acpi:
Top causes for wakeups:
99.5% (20393.4) [acpi] <interrupt>
0.2% ( 33.0) [iwlwifi] <interrupt>
0.1% ( 22.4) [Rescheduling interrupts] <kernel IPI>
My questions are: a) Is this normal? And if not, b) does anyone know what I
can do about it? I came across a bug report that makes me think this should
not be happening: https://bugs.archlinux.org/task/28859
I'm not sure what the 20393 refers to, but I suspect it is the number per
second, since it doesn't seem to change much, irrespective of the polling
interval I use.
Thanks in advance for your help : )

Top causes for wakeups:

ACPI Interrupts occupy one core totally

Hello.
I have a Samsung NT700Z5C-S78 laptop bought about one and a half years ago.
(btw, I replaced the laptop's HDD with an SSD (Samsung SSD 840 EVO).)
Recently, I have noticed that the System process uses 100% of one core, so I did some research through Google, and have tried:
- cleaning-up dust inside the laptop
- editing "HKLM\SYSTEM\CurrentControlSet\Services\ACPI\Parameters\Attributes" key to 100 or 70 (HEX)
- upgrading the bios
- installing Windows 8 cleanly
- upgrading to Windows 8.1
- re-installing Windows 7
- disabling the device "Microsoft ACPI-Compliant Control Method Battery"
but still the same.
Process Explorer says that "Hardware Interrupts and DPCs" occupies the core,
and LatencyMon shows ACPI.sys is the problem.
Can anyone help me to resolve this?
Here is the etl file from my laptop:
https://skydrive.live.com/redir?resid=2CCEBED319172246!328&authkey=!AGKgHDq9w8BqkF4&ithint=file%2c.zip
Thanks.

Hi，
The file, ACPI.sys, is a system driver that is used to facilitate the advanced power management features of the motherboard. There appears to be a conflict on your system between the BIOS and the driver layer of your system. Please ensure the BIOS and motherboard
chipset are up-to-date and they support Windows 7.
If the issue persists, you may try to disable ACPI for a try: when you start your computer. Then, open the Power Management Setup menu. And find ACPI, select "NO" to "ACPI Aware Operating System". After that, just
type Exit and begin the installation process again.
According to your etl file, I found this process got High disk usage:
http://www.file.net/process/dmhkcore.exe.html

[SOLVED] /dev/video0 no longer shows up in my system.

I have been running arch on my laptop for about a year or two with no problems. The laptop I have has an inbuilt webcam that I used to be able to use fine.
I haven't tried to use it in about a month or so but I just did and it appears completely blank. I try to check things are alright and can no longer find /dev/video0 which is where it used to show up.
looking at the wiki page it says to identify your webcam with lsusb but I assume that is only for usb webcams rather than inbuilt ones. I also tried looking at my dmesg but can't find anything looking like a webcam. How can I debug this and where should I look for information on how to set this up?

I just were about to do so, but tu ensure that there isn't already a new thread about that i searched for it and found a also solved thread, but as i saw the user trying to accses his webcam by typing fswebcam, i tried it too and came to the point that i didn't have installed that. To see if i would get the same errormessege as he did i installed ist via pacman and tried again to run it:
$ fswebcam
--- Opening /dev/video0...
stat: No such file or directory
then pressed the webcamkey...
$ fswebcam
--- Opening /dev/video0...
stat: No such file or directory
...pressed it again...
$ fswebcam

Adjusting resolution from 384x288 to 352x288.
--- Capturing frame...
Captured frame in 0.00 seconds.
--- Processing captured image...
There are unsaved changes to the image.
so at last there wasn't any error at all.
after that i tried typing
$ ls /dev/ |grep video
video0
so my webcam was there again, and worked in cheese too. The only other actions i did befor taht were again a pacman -Syyu which only updated my flashplugins and git and also a system reboot (nautilus stopped working and after restarting nautilus it wasn't recognising inserting my microSD, or a USB-flashdrive, so i tried to reboot). After all of this i don't know why it helped
pacman -Syyu couldn't couse that as far as it din't update anything the webcam is depending on
a systemreboot just reloads all kernelmodules and restarts the applications - the new modules after kernel update had to be loaded before as i did serveral reboots since then
installing fswebcam can't change anything that couses /dev/video0 to appear
But thank you anyway!

[SOLVED] Openbox+Thunar, how to show usb devices in thunar?

Hi. I've been running a pretty standard Xfce environment for a while. When I plug in a usb drive, I get a new item pop up in the "DEVICES" section of the left panel in thunar (note, it doesn't automount the device, it just shows that it's there and only mounts it when I click on it...I like this behaviour).
Now, I'm setting up an even lighter-weight environment, just openbox and tint2 with thunar as the file manager. But when I'm logged into the openbox environment, I don't get the item in the "DEVICES" section in thunar (but it still works fine in xfce).
If it run thunar from the command line and plug in a usb drive I get this message in the terminal
(thunar:21205): thunar-WARNING **: Failed to launch the volume manager (Failed to execute child process "thunar-volman" (No such file or directory)), make sure you have the "thunar-volman" package installed.
I don't see why I would need thunar-volman if it works fine in xfce. If I install thunar-volman and do the same, I get this message
thunar-volman: Unsupported USB device type.
thunar-volman: Unsupported USB device type.
thunar-volman: Unknown block device type.
So I'm wondering if maybe there is a daemon that is autostarted during an xfce session that makes thunar probe for devices to be plugged in or something like that. Why does it work in an xfce session, but not in an openbox session?

Thanks for your replies.
henk: I tried installing polkit-gnome and creating the rule as per the wiki, but it didn't work. Volume detection seems to work fine in xfce without this package.
jv2112: I added udiskie to .config/openbox/autostart and it seems to work. I've had problems with udiskie in the past; it seemed to have some trouble unmounting the drives properly after a write as I would find that the newly written files were corrupt. But it seems to be working fine.
I'll mark this as solved, but I'm still curious as to how xfce-thunar is mounting the usb devices.
One clue is that with udiskie, devices get mounted to /media, whereas in xfce they get mounted to /var/run/media/username/ (or something like that).

Camera tracker solving without errors but not showing result points

hi
I am trying the new camera tracker in AE cs6,
im using very simple shots that can be tracked easily,
and im having some strange behaviours,
basically in many shots the analysis takes places with no errors but after the camera solve no result points appear, even if i use the advanced mode , changing all other parameters etc, and no errors are reported anywhere, also i select the effect on the panel and i also make sure the points size parameters are scaled up,
but if i click on processing points (the unchecked box below 3d solve) i can see they are all there, and i can also create camera and the camera is created, so its as if all the process takes place correctly but for some reason the solve points are not shown on screen
it has happened to me that with same shot sometimes they appeared and sometimes not, but most times they dont
what can be happening in here?
thanks so much

will try to explain better my problem
if i click on
Render Track Points
i can see there are great track points that follow all the movement perfectly,
and yet without checking that box no solve points appear, even when i select the effect on effects panel
or change any other parameter or do the advanced mode
i can still click on create camera etc, but i cannot attach a text etc to a specific solve point because no solve points appear
and yet as i say, if i click on the Render Track Points box i can see great tracking points all over the place following the action
so the fact that selecting Render Track Points on effects panel shows great perfect points following all , does that confirm that camera solve was successful?
i just cannot understand why i cannot see any solve points that i can interact with
i have tried to scale sizes all the way up, select effect on panel and hundred other things
thank you for any help

hi there Naveenlndian
this is not a fault your battery needs to be replaced, to keep the life of your battery for longer take it out when you have the laptop plug in or it will kill your battery. if you have your battery in and the laptop plug in as well wot happens is wen the battery is full your laptop will switch it self from manes power to battery ther for using the battery till it need to charged agen. then it will switch back to manes and charge it agen. this is a constant circle so the more it dus it the power is lost from the battery. so the best way to keep your battery life for aslong as poss is to charge it, take it out then leave it out till you dont have access to a plug socket. the only problem with this is if you have a power outage wile your plug in to the manes and no battery your laptop will just go off as there will be no battery in your laptop.

Lots of RTC interrupts according to PowerTop

I'm currently running into a strange issue with my new Thinkpad X250:
When returning from suspend-to-ram _for the second time_ the RTC is starting to generate lots of interrupts, with powertop listing it as the top cause of wakeups when my laptop is completely idle. This doesn't happen when I boot the kernel with hpet=disable.
Is there any chance to find out what's causing this? (I'd be more than willing to provide debug output, but I have no idea where to start)
This is happening on all current versions of the kernel (4.0.4, 4.0.5, 4.1-rc8), and just for kicks I tested this with the latest install disc as well with the same results (so I can probably rule out a specific application as the issue).

[Solved] Pacman message after interrupted installation... persists

As you can see I'm still a bit of a newbie. Yesterday I was installing TeX live, but while installing someone unplugged a USB stick and all went stuck... it all just freeze the system, I guess it was a hardware problem. Anyway, I restarted and when I came back to resume the installation (downloading of packages was already finished), pacman sent me a lot of error messages, but apparently TeX live installed fine. Well, I checked my TeX system and works fine. The problem is every time I try to install something, I always get this error message:
error: could not open file /var/lib/pacman/local/texlive-bin-2010.1-4/depends: No such file or directory
error: could not open file /var/lib/pacman/local/texlive-bin-2010.1-4/depends: No such file or directory
How do I repair this? I didn't want to clean the cache, but... would this do fine? what else do I have to do?
Thanx in advance.
Last edited by joe74 (2010-10-23 22:33:20)

Well, solved by myself.
What I had to do after a lot of mess was
1. uninstall everything that was causing errors
sudo pacman -Rs texmaker texlive-most texlive-core texlive-bin
2. and clear the cache of files not installed
sudo pacman -Sc texmaker texlive-most texlive-core texlive-bin
This solved the entire problem. Dialectical theory still functioning in my brains

[solved] who command doesn't show X server session

Hi there,
shouldn't the `who` command show all logged in user sessions, including my X server session?
However, who only shows my tty1 session:
[orschiro@thinkpad]$ who
orschiro tty1 2013-10-25 17:01
What is the output of who on your system?
Last edited by orschiro (2013-10-27 20:21:32)

Alright. The point is, what do I need to do in order that who shows my X session?
I tried export DISPLAY=:0 but this doesn't add :0 to the who command listing.
The reason I am asking is that I want to use the following dispatcher script which queries for :0, assuming that who shows the display variable.
#!/bin/sh
INTERFACE=$1 # The interface which is brought up or down
STATUS=$2 # The new state of the interface
case "$STATUS" in
up) # $INTERFACE is up
USERS=$(ps -o user --no-headers -C dropbox)
killall dropbox
for user in $USERS; do
su -c "DISPLAY=$(who | sed -e "/$user/! d;/pts/d;s/^.*[^0-9]\$:[0-9.]\\+\$.*$/\\1/p;d" | head -n1) dropboxd &" $user
done

[solved] nm-applet does not show up in Gnome panel

Hi all,
I installed networkmanager, network-manager-applet and dbus this afternoon. As well as a fresh install of Gnome. This is all done on my laptop, which my wife wants to use now and then. I always set up the network CLI, but now I will need a nice flashy applet in the Gnome panel.
I managed to run the network-connection-editor as root, and got the network up.
I had some dbus problems when I tried launching nm-applet, but fixed it with a dbus-hack I found in some other thread. But when I now launch nm-applet, it says that there allready is an instance running of nm-applet.
I guess it should show up in the panel, if it is. But I don't see anything there... Do you have any ideas of what I forgot to install/configure/check.
Thanks,
jocom

There have been a couple similar posts recently. I'm not using Gnome anymore or networkmanager, so I don't know if there's a problem with it or not. If I remember correctly I had to install gnome-panel-bonobo, and I believe python-notify and gksu too. You can do a search on the wiki for networkmanager, there is a page for it that explains the configuration changes you'll need to make. Hope it helps.
