I just booted windows and re-applied the new BIOS (1.3.3) and the new Thunderbolt Firmware so I am all caught up on the BIOS and firmware settings on the board.
I also nuked all the HD and re-installed Ubuntu from scratch. I just retested it and the crash still happens when you close the lid or issue a suspend commend using the UI. This is a critical regression that should be addressed and soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572723 Title: Dell XPS 9350 Reboots upon resume with the latest 4.4.0-21 kernel update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1572723/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
