Verified again with this system re-installed, this issue still 100% reproducible on 3.2.0-99.
Steps: 1. Re-install the system with --proposed. 2. Run the gpu_lockup_after_suspend on it. Result: * For the very beginning, when it crashes on the gpu_lockup_after_suspend job, it will reboot itself automatically. And I finally see this error message: Unable to handle kernel paging request. When this happens * Caps Lock LED was not blinking. * the system seems frozen, it does not react to NumLock / CapsLock / VT switching and ssh connection. * system can still take the magic key to reboot (Ctrl + Alt + PrtScn + b) (I think the kernel is still alive, so the error can be logged) ** Attachment added: "paging-request-2016-Feb-19.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1546985/+attachment/4575367/+files/IMG_20160218_171801.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1546985 Title: BUG: unable to handle kernel paging request at ffff87ffb88dbf18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1546985/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
