Hi, I can test only on live image but can't install developpement release on my computer. I gonna test in a couple of days, and let you know the test result.
But testing this problem might a bit hard because it is a random problem and hard to reproduce. If I got any error, I'll try to get some debug info. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1271540 Title: Random "Watchdog detected hard lockup" when resuming from suspend Status in “linux” package in Ubuntu: Incomplete Bug description: 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. --- ApportVersion: 2.12.5-0ubuntu2.2 Architecture: amd64 AudioDevicesInUse: 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.
