Public bug reported: Since about two weeks my system has repeatedly crashed completely without any error notice. The screen freezes and no keys respond. I have to shut down the computer pushing the button to turn it on for a couple of seconds. On reboot, I usually get the error message
PXE-E61: Media test failure, check cable PXE-M0F: Exiting Intel Boot Agent But usually Kubuntu boots after that without problems. Sometimes I have to Ctrl+Alt+Del to get boot going. I have no idea what causes the crash, it happens suddenly and without any hint about what triggers it. I attach the content of /var/log/syslog right before the crash from a couple of times it happened. I am running Kubuntu 16.04.3 LTS with Kernel 4.13.0-31 on a ThinkPad T460s. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: bot-comment ** Attachment added: "Output of Syslog after reboot right after crashes" https://bugs.launchpad.net/bugs/1745814/+attachment/5044397/+files/freezes-syslog-after-reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1745814 Title: Kubuntu crashes repeatedly without error notices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1745814/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
