I've tried the kernels you mentioned and: - v3.12 final worked - v3.13-rc3 didn't work
The problem is that the bug behavior changed after a couple of reboots. I was trying to take a photo of the error messages but I couldn't get a clear photo and after a few reboots, the error wasn't displayed anymore and the laptop booted until the login screen (LightDM), then it freezes. Once I was able to log in to the Unity desktop and only then the laptop froze. So basically now the laptop freezes when the login screen shows up when using v3.13-rc3 as well as when using the initial kernels that caused issues (3.13.0-1-generic, 3.13.0-2-generic and 3.13.0-3-generic). Unfortunately, that means I couldn't take a photo of the old error but I'm attaching the syslog, maybe you can find something helpful there. Let me know how else I can help... ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1269404/+attachment/3949999/+files/syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1269404 Title: BUG: soft lockup - CPU#2 stuck for 22s!
