It would be good to know if when using the threadirqs parameter is a regression. If that is the case, we can bisect to identify the commit that introduced this.
Can you test the following kernels with the threadirqs parameter enabled and post back if any do not exhibit the bug: v3.2 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/ v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/ v3.8 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring v3.12 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-trusty/ You don't have to test every kernel, just up until the kernel that first has this bug. If 3.2 has the bug, no need to test the rest.

I have the crashdums, but I figured that it might have been solved in 3.13. Unfortunatly it seems like it is not. I will add crashdumps when I get crashes that do not just lockup the machine but currently I have only seem complete lockups with 3.13 So the essense is : 3.11-lowlatency crashed 10 time today most of the crashes reached the console so I could see the panic text. 3.13-lowlatency crash 1 time 10 minuttes after first boot. No VT swtich. During next reboot it also locked.
