As I reported a duplicate of this: hard to say, as the bug was reported automatically without my being aware of anything amiss.
I have seen odd lock-ups after resume from memory, most recently a week or two ago, though I don't know whether they are the same issue - it is hard to work out anything useful about them, as the backlight is not enabled, I can only just see that the laptop is stuck in text mode with what might (but I can't be sure) be a kernel panic backtrace, and the crash kernel which I installed and tested via sysrq obstinately refuses to start (as far as I can tell with no backlight). (Any thoughts, including possible alternative bugs to listen in on are welcome.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/839338 Title: [arrandale] GPU lockup render.IPEHR: 0x01820000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/839338/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
