Bug ID: 82711 Summary: After update to kernel soft lockup and incomplete boot Product: Drivers Version: 2.5 Kernel Version: 3.16.1-1-ARCH Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: mike.cloaked@gmail.com Regression: No
Created attachment 147021 --> https://bugzilla.kernel.org/attachment.cgi?id=147021&action=edit 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.
