Public bug reported: This kernel lockup bug was reported to and fixed upstream: https://bugzilla.kernel.org/show_bug.cgi?id=81841
Please backport the "stable" kernel patch to Ubuntu kernels (at least trusty, which I use in this setup): https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=9b29d3c6510407d91786c1cf9183ff4debb3473a ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-35-generic 3.13.0-35.62 ProcVersionSignature: Ubuntu 3.13.0-35.62-generic 3.13.11.6 Uname: Linux 3.13.0-35-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.13.0-35-generic.
