Unrelated to this bug, I have also discovered that alt+sysreq RIE are all disabled for the mainline and trusty 'head' kernel (3.13.0-20-generic) by default:
cat /proc/sys/kernel/sysrq 176 Mentioned here: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/1025467 Also, if I suspend while the focus is on tty1 ( a text console ) rather than tty7 (GUI), the text console operates fine when I resume from pm- suspend until I switch back to tty7. At that point the system locks up again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1299821 Title: [LENOVO 4236SGS] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1299821/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
