Here is little piece of oops from the link above:

Also here is my lspci [2] and cpuinfo [3] as well.
Vanilla 3.15.8 and 3.16.0 are affected as well as latest Ubuntu 3.13
kernel.
No visible reason to trigger the bug. After hang machine doesn't respond via
network, there's no disk IO, and also it doesn't respond to pressing power
button in order to perform soft off.
And here is kernel bugzilla bugreport [4].
