It does not occur anymore for me (kernel 3.13.0-21). I couldn't get from which update the issue disappeared but now everything's fine.

*** This bug is a duplicate of bug 1275116 *** https://bugs.launchpad.net/bugs/1275116 Hi, I still have this soft lockup bug with kernel 3.13.0-17 (no matter if it's the lowlatency flavour or not, hence not a duplicate of bug #1275116, which seems resolved now). Joel and Alin, do you still have this bug? However in my case, this threadirqs is not present in my /etc/default/grub, so that might not be the same bug. Another clue: I run a dual graphics hardware (sony vaio Z12 laptop, nvidia+intel). The bug does not occur when I set the BIOS to static in order to force the nvidia card to run. So it might be related to the intel graphics driver. Should I open a new bug, or is there any known fix or workaround?
