[2in1/Medion] systemd-udevd eating my cpu (100%)

hi,
i got a medion P2214T (MD 99480) 2in1 laptop/tablet (u can undock the keyboard) but when i undock or dock the keyboard, systemd-udevd goes crazy and use 100% CPU.
if i UNDOCK, udevadm monitor shows permanent:
KERNEL [numbers] change /devices/platform/dock.0
if i DOCK, udevadm monitor shows permanent:
UDEV [numbers] /devices/platform/dock.0

Turned out to be an issue with libdrm. Apparently I had run some updates yesterday before shutting down, but they didn't appear in pacman.log; instead I found them by looking in the pacman package cache and found:
-rw-r--r-- 1 root root 110072 Jul 29 22:59 lib32-libdrm-2.4.56-1-x86_64.pkg.tar.xz
-rw-r--r-- 1 root root 160996 Jul 29 22:55 libdrm-2.4.56-1-x86_64.pkg.tar.xz
Downgraded [lib32-]libdrm packages to 2.4.54-1, rebooted, and success.

[SOLVED] systemd-udevd using 100% CPU and monitors go to sleep on boot

Hi,
Turned my PC on this morning to find an issue with the monitors going to sleep immediately after booting. The boot process is usually slim autologin to a cinnamon session. I can see as far as entering my LUKS passphrase, followed by a few additional lines, followed by blank monitors and monitors entering power saving mode.
Booting with nomodeset on the kernel command line allows me to boot to a terminal and I can login etc, but obviously X doesn't start. I'm using xf86-video-ati drivers.
When booting with KMS enabled I also have a runaway systemd-udevd process which is thrashing my processor and I'm unable to kill it (I've tried kill -9 and still it persists).
The PC was working fine when I shut it down last night. No updates have been performed since, and no configuration changes have been made. I did notice that the power management dialog in the settings failed to open though.
Any suggestions would be welcome please, as I've now lost half a day trying to get this resolved.
TIA
X.
Edit: I've also tried downgrading xserver to 1.15, xf86-video-ati and the associated dependencies with no change.
Edit2: I've also disabled slim and rebooted and the same thing happens - so I don't believe it's an issue with X but with KMS.
Edit3: Booting with acpi=off on the kernel command line also fails with the same result.

[SOLVED] systemd 208 journald process CPU spike on LXC container start

Hi,
The problem is that whenever I start an LXC container, systemd-journald process goes on 100% CPU utilization and only stops when I stop the container.
Setup details:
% cat /var/lib/lxc/projects/config
lxc.network.type = veth
lxc.arch = x86_64
lxc.utsname = projects
lxc.network.link = virbr3
lxc.network.flags = up
lxc.network.ipv4 = 192.168.200.11
lxc.rootfs = /mnt/lxc/projects
lxc.pts = 1000
lxc.autodev = 1
lxc.cgroup.memory.limit_in_bytes = 256M
The rootfs indicated is on a logical volume, /dev/mapper/virtual-projects.
Details of journal when the spike happened:

Nothing really leaps out to me.
This only happens on Systemd-208. Rolling back to systemd-207 resolved the issue for now, but I can't help but wonder if I won't have this problem again on systemd-209 or whatever. Is there any additional configuration that I need to do in order to get LXC working properly with systemd 208+?
Also, I don't know if this is relevant, but I got some filesystem permissions warnings on upgrading (and later downgrading) systemd.

Since i up graded to itunes 10.5.2 i cannot access itunes store fully ,i have apple mobile device exe eating my cpu at 97% and now i tried to sync my ipod and it said that i needed to restore my ipod ,this i did and now i cant access my ipod library

this has got ridiculous now i cant access itunes tore,my ipod says there is no music on it even though i watched it sync nearly 5000 tunes and the program apple mobile device exe eats my cpu at 97% it slows my computer to a crawl should have had the courage of my convictions and stuck to itunes version9 at least that worked.tried resetting netsh winsock,flushing my dns all not worked.this has to be sorted out...and quick

Hi,
I have tried and confimed that you can download the previous version from some web-site about the version 10.5.1.42.
Remove/un-install 10.5.2.11 and restart your computer.
Install the old version 10.5.1.42
and then you can find the "Devices" on the left column and showing synchronizing when you connect the cable.
Good luck

ITunes eats up CPU

My iTunes eats up CPU (95%-142%) while converting from MP3 to AAC!?
18 tracks (134 MB) is not to much I assume!
Fans on my MacBook Pro 17" are working non-stop (at 5800-6000 min.Speed) during this "operation"!
Is there a particular reason or there is something wrong with my laptop?

Yeah same problem here. The only thing I've been able to do to deal with the problem is to close out of mozilla firefox (or any other larger program), and it usually improves... kind of a pain.

Thanks for the reply! So what I do? Just replace all SYSFS tags with ATTR tags? Is that correct?

CPU 100% When Playing Minecraft iMac

Hi There!
As the title says, "CPU 100% When Playing Minecraft". Every time I boot up Minecraft the Fan becomes loud. I have another iMac (Late 2013) Model and it runs Minecraft fine with all the same settings. So I don't really no what to do. But if you could help me try to get the CPU usage down or maybe turn the fan down? Or something like that that would be great!!
My iMac Specs.
Mac (Retina 5K, 27-inch, Late 2014)
Processor: 4 GHz Intel Core i7
Memory: 32 GB 1600 MHz DDR3
Graphics: AMD Radeon R9 M295X 4096 MB
So Yeah, if you could give me a hand, I would be so much appreciated!
Thanks!

Firefox 3.6.6 Windows XP - often goes to 80-100% CPU even with only one tab open (in this case the one I'm writing this message on). When this happens the only cure is to kill it with task manager and start again.

Systemd-udevd Error

Since the latest systemd updates I am getting this error from initram:
systemd-udevd[247]: Error calling EVIOCSKEYCODE: invalid argument
It does not get logged in journalctl, so I typed it off from the screen...
Not quite sure what this means? My system seems to be working o.k. but this is a little bit embarrassing...

This is only true of systemd in [testing]. OP Never stated what version of systemd they were using.
Assumption taken because post is in testing forum.
Version 206 confirmed by the complete output that Harey has posted:
Aug 14 16:39:11 obelix systemd-udevd[57]: starting version 206
Harey,
Possibly the logging is not to be enabled on kernel command line but via /etc/udev/udev.conf i.e. set udev_log="debug" in that file.
Can you try with that (not sure it will work with initramfs, it's something I don't really understand) ?
Cheers

[SOLVED] systemd-udevd renames network interfaces

During install I enabled dhcpcd service like this:
systemctl enable [email protected]
Seems perfectly valid, eh? But after reboot network I've got the following messages:
[ TIME ] Timed out waiting for device sys-subsystem-net-devices-eth0.device.
[DEPEND] Dependency failed for dhcpcd on eth0.
dmesg | less
systemd-udevd[111]: renamed network interface eth0 to enp0s3
It appears systemd changes network interface names. But then I suppose [email protected] is to be removed:
[Unit]
Description=dhcpcd on %I
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device
[Service]

PIDFile=/run/dhcpcd-%I.pid
ExecStart=/usr/sbin/dhcpcd -q -w %I
ExecStop=/usr/sbin/dhcpcd -x %I
[Install]

old to Linux new to archLinux
jasonwryan -thanks!
Your post helped me figure it out why my Ethernet interface name was changed to enp0s3 and why - I like the old naming convention ethx easier for me to remember. So went the route with custom rules in /etc/udev/rules.d
Here is what I used.
70-my-net-names.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="08:00:27:3b:f3:cd", NAME="eth0"

MassStorage process eats my cpu

Hi,
since i installed 10.4.8, my system has been behaving in a strange way. Iphoto now recognizes my firewire mass storage (160 gb hard disk on an enclosure) unit as a camera... and i notice that the MassStorage process (as i see it in activity monitor) get to use 30% or 50% of Cpu (intel imac 17 inch), until it gets stuck "not responding" and it goes up to 80%. After i kill the process, everything goes back to normal. The thing is, i use the storage devide very much, and even when the system starts i see it eating my cpu.
how can i resolve this? is there any known workaround? i dont think it is a normal behaviour, its been happening since yesterday.
Thanks in advance.
Alberto Rojas

Ok, so spotlight indexed my hard drive again, and i let massstorage to finish its work. I know the process is directly related to the indexing process, but i cant make it stop. The indexing setting is set to off (through terminal) but it keeps working everytime i restart, even in the admin account in my mac, and even after the process is finished. There has to be a workaround, im still looking around for answers.
thank you very much for your help.
Alberto.

VBoxSVC eating my CPU

Today I tried to do some work on my VMs, but after loading drivers:
sudo modprobe vboxdrv
sudo modprobe vboxnetflt
sudo modprobe vboxnetadp
sudo modprobe vboxpci
and starting VirtualBox then VBoxSVC starts eating my CPU. So I can't do my work.
Has any one fix for this? I saw the more users have faced this problem but without any solution...

Other than that google "ODSAgent" for other links.

G580(20150) CPU 100%

При добавлении или уменьшении гровкости, а так же яркости экрана с помощью кнорки Fn +нужная стрелочка вылазит сообщение. В заголовке написано "Energy Managment", сообщение внутри окна"CPU 100%" и кнопка "OK". Посмотрев по диспетчеру задач процессор не загружается на 100 процентов, а просто выскакивает окно. Которое мешает постоянно. Как исправить? Спасибо заранее за ответ.

Приветствую
Никаких других идей, кроме удаления и переустановки драйвера Lenovo Energy Management лично у меня нет. Вы не назвали ОС, для win8.1, например, есть два разных релиза, для разных платформ ноутов. Для 20150:

Disconnected users eating 25% CPU time

Hi,
Some times my wife stay logged in on our common computer (she wants keep open her files). When I log in her account is disconnected. If I do not so any think on the computer the CPU load is about 25%. I checked the task manager, my wife's disconnected account
eating this CPU time. I checked the process, it is "Windows Logon User Interface Host".
I have 4 core CPU. It seems there is thread in the "Windows Logon User Interface Host" which is in an infinite loop. I am using Windows 8.1 with the latest updates.
It would be nice, if a Windows service does not eat CPU time just for nothing.
Best Regards.

Hi，
Do you use remote desktop connection? sometime, a incompatible 3 party remote desktop application can cause a high logonui.exe cpu usage.
And software like A-Tuning can also cause this issue, if you have this softwware installed, I suggest you uninstall them, then test again.

CoreCenter eating 99%CPU

Hi,
I have an MSI K8T Neo2 FIR motherboard. It was recently replaced by a new one because the old one had a problem that the CoreCenter application was eating 99% CPU when started and would not display its GUI. Originally I used the old board with a relatively weak PSU, and then it sometimes rebooted, but after replacing the PSU with a stronger one, it became perfectly stable and has been so for 6 months. The fault causing 99% CPU usage with CoreCenter occured with the weaker PSU after booting it 2-3 times, so I suspected that the fault was due to the weak PSU.
I got the motherboard replaced recently. CoreCenter worked well for a while (a few hours), but then, after a reboot, the old symptoms appeared again. I don't think the PSU is the problem this time, so I started some investigation with SoftICE to see where it runs when it is using all CPU time. It turned out that it repeatedly calls the HalGetBusData system call querying the PCI configuration space. The PCI bus number is always incremented between the calls. So it looks as if the program is looking for some device, but doesn't find it.
What could be the problem? Could it really be that some device (e.g. the CoreCell chip) got faulty and no longer shows up on the PCI bus (though AFAIK the CoreCell chip is not on the PCI bus)? How can I further check what the problem and most importantly its root cause might be?
Thanks,
István

I tried both the one that came with my motherboard (something like 1.7) and the latest one. However, I doubt it has to do with the version, since it worked for a while. And then something happened and it ceased to work. I suspect that something happened to my motherboard, since I had the older one with the same problem, and after replacing the motherboard (and only the motherboard), the program worked for a while and then stopped working.
I would like to figure out what could have caused the problem.
