Hope the following description belongs to this bug, couldn't easily find something more similar:
After a fresh install of 17.04 (with standard packages) on my Dell Latitude E7240 some 10 days ago, my system seems to show similar phenomena, however, I could recognise that the final freeze is a consequence of a staged process happening beforehand: 1. E.g. (T)hunderbird or (F)irefox is getting what is (afaik) called a Zombie process, however, instead of "Z", T/F are marked with "D" (for disk) in top, running at 100% and not killable via top or kill -9/-15. 2. Machine load is slowly going upwards (within 4-5 min or so) until I can't switch windows or desktops anymore, neither can I switch to the text console to initiate an ordinary "shutdown (-R) now". 3. I have to perform a hard ACPI reset per button. This happened already 4 times since I have installed 17.04. According to what I found on the web, https://unix.stackexchange.com/questions/5642/what-if-kill-9-does-not-work it seems to be a peripheral/driver/filesystem/interrupt related problem. However, this exceeds my knowledge. Hope to get some help, or hope to have contributed worthy information. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686329 Title: System freezes randomly after upgrading to ubuntu 17.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1686329/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
