dmesg showing the crash, CPU 2 is stuck

Hi!

ii  libdrm-intel1: 2.4.58-2     amd64        Userspace interface to intel-spec
ii  xserver-xorg-v 2:2.21.15-2+ amd64        X.Org X server -- Intel i8xx, i9x

Linux eizo 3.16-2-amd64 #1 SMP Debian 3.16.3-2 (2014-09-20) x86_64 GNU/Linux

>From time to time, I get a crash when starting a video in XBMC. This is not
easily reproducible. Nothing in xorg.0.log. Once crashed, X.org is freezed but
the remaining of the CPU seems to run correctly as long as they don't need to
query stuff on the stucked CPU. See the attached dmesg.

Maybe this is related to this bug reported in the Debian BTS:
