** Description changed: - Hi, + I encounter a bug when suspending my computer : everything suspends + properly when I press the sleep button on the keyboard, but sometimes + the computer freezes when I wake it up (by hitting the power button). So + I have to power off the computer by long press on the power button, or + reset the computer. I tried to suspend with the pm-suspend command, I + got the same result. I tried to suspend through a TTY, and here I was + able to get some logs (I took a photo of the log, attached to this bug + report). The error message was the watchdog detected a hard lockup on + the cpu (8 core cpu, so I got several times the message). The faulty + software seems to be systemd-udevd, according to the trace I got. I + noticed also this problem related to suspend : I use virtualbox and if I + suspend computer, resume it and try to launch a VM after, I can't get it + running properly : it is very slow and I have to reboot the computer to + get it working properly. And I noticed also if I have used a VM and + after I suspend the computer, I am almost sure I'm gonna have a freeze + when I wake the computer up. - I encounter a random bug when suspending my computer : everything suspends properly when I press the sleep button on the keyboard, but sometimes the computer freezes when I wake it up (by hitting the power button).

I googled a bit the problem, but wasn't able to very usefull information - - I wasn't able to find anything about the message I saw on the screen in - the log files. No record at the time of the freeze. That really - surprised me. - - I noticed also this problem related to suspend : I use virtualbox and if - I suspend computer, resume it and try to launch a VM after, I can't get - it running properly : it is very slow and I have to reboot the compter - to get it working properly. And I noticed also if I have used a VM and - after I suspend the computer, I am almost sure I'm gonna have a freeze - when I wake the computer up. Maybe is there something related ? - - This problem happens randomly but I didn't find anything to reproduce it. - Here is the configuration of the computer : - -mother board : MSI h77ma-g43 - -cpu : intel core i7 ivy bridge series - -ram : 16 gb - -using onboard soundcard and video card - -1 hdd 1.5 tb on sata 3 - -another 1 tb hdd on sata 3 - -bluray/dvd burner on sata - - Using Kubuntu 13.10 x64 everything up to date. - - Does anybody get the same or a similar problem ? - If any more information is needed, please feel free to ask. - --- + --- ApportVersion: 2.12.5-0ubuntu2.2 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: vincent 2337 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: vincent 2337 F.... pulseaudio DistroRelease: Ubuntu 13.10 HibernationDevice: RESUME=UUID=f11f8578-3772-463c-b3ec-e7ec4307cbe3 InstallationDate: Installed on 2012-06-02 (599 days ago) InstallationMedia: Kubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120423) IwConfig: - eth0 no wireless extensions. - - lo no wireless extensions. + eth0 no wireless extensions. + + lo no wireless extensions.
