journalctl from last couple of boot/hang cycles

This could be interesting:
I've been bisecting. The first usable kernel on Cayman with dpm was between
3.11-rc1 and 3.11-rc2. Before that, the system was unusable (major corruption).
So, with patches from related bug, I was able to start a session and run
applications until it hanged.

On Nov 15 00:19:51, I was booting with a safe kernel (before dpm was enabled,
a144acb).

On Nov 15 00:36:23, I booted with the kernel exhibiting a desired behavior.
Logged, ran tasks, hanged on Nov 15 00:41:03. Segfault in libLLVM-3.3.so and
possible recursive locking detected, followed by DEADLOCK.

However, I was unable to get the same result in the following boot.

Then switch to 3.12-rc7 to send journal.
