https://bugzilla.kernel.org/show_bug.cgi?id=82711 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@xxxxxxxxxxxxxxxxxxxx Reporter: mike.cloaked@xxxxxxxxx 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.

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. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
