Systemd journal log after rebooting from crashed system

After update to the kernel 3.16.1-1-ARCH the Lenovo Y510p with hybrid
Intel/Nvidia graphics fails to boot though occasionally boot does complete and
when it did then partial logs were available from the systemd journal despite
having to pull the power to shutdown the system which corrupts the journal
files.

CPU soft lockup is one part of the log, and it seems that the graphics card
fails to initialise properly also.

Graphics cards are:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 750M]
(rev a1)

I was not sure which components to select for this report so chose non Intel
DRI - if necessary that can be changed.

Either way when the bug hits during boot the VTs fill with log output but it is
not clear that the logs contain all of the diagnostic information but the
attached log file is all that I was able to capture.
