Looking at the big picture: What concerns me most about this bug is the way it deadlocks all of Linux. The console does not respond, there is no normal crash dump, etc.
My thoughts are: We could try a non-Ubuntu kernel? One compiled from source or another distro. And see if there are open bugs that other non- Ubuntu users have opened. Also some strategy for allowing remote kernel debugging or tracing (on just Intel GPU driver?) to try to figure out where the deadlock is happening. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575467 Title: [Dell Inspiron 3451] WARNING: CPU: 1 PID: 1297 at /build/linux-lts- utopic-vy2yyy/linux-lts- utopic-3.16.0/drivers/gpu/drm/i915/intel_display.c:1743 vlv_wait_port_ready+0x126/0x170 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1575467/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
