The machine was apparently in sleep mode after this but I could never get it to resume properly (hard lockup, sysrq didn't do anything). The only notable difference here, was that I logged out before suspending. On the resume attempt, I saw a corrupted login page but the machine was completely unresponsive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/890303 Title: [i915] stack trace on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/890303/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
