** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Package changed: linux (Ubuntu) => linux-oem-5.6 (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1919425 Title: System freeze Status in linux-oem-5.6 package in Ubuntu: New Bug description: I've been getting freezes on Ubuntu 20.04 on my Dell Latitude 7420 laptop with a secondary display connected through a WD19 Dell dock. I'm on the supposedly-certified 5.6.0-1048-oem kernel, have tried 5.8 and 5.10 without much success (other types of freezes). Some freezes lock up the machine hard with no way to ssh in or check anything and no logs. The one below I was able to ssh in and dump dmesg, rebooting via ssh froze and I had to do a hard reboot.
