This issue could not reproduce with an AOC E2460SW Widescreen (24" 1920 x 1080 16:9).
I tried to reproduce by the following steps: 1. Enabled the proposed pocket, and updated the system via GUI updater. 2. After updating the system, reboot. 3. Plug-in the aforementioned monitor in the HDMI jack of the XPS15. 4. Check dmesg and /var/log/syslog. The panic message could not be found in both of them. The screen of external HDMI monitor and the internal monitor looks good as well. 5. Suspend the system by the desktop indicator. 6. After the system resumed, repeated the step3. I got the same result as the step4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1658999 Title: [Xenial Regression] Kernel panics on HDMI in Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1658999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
