The function "intel_ddi_pre_enable_dp" has changed significantly from 5.4 to 5.8. You can try 5.8 kernel (https://people.canonical.com/~alexhung/LP1900377/groovy/, used in 20.10 and perhaps future 20.04.2) or latest 5.9 mainline (https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9.1/) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1900377 Title: System froze after wake from sleep Status in linux package in Ubuntu: Confirmed Bug description: I have a Dell XPS 9300. After waking from sleep, the machine froze (unresponsive to keyboard and mouse) and needed to be restarted. I've attached logs from running: journalctl -b -1 --no-hostname -k > ~/dmesg.txt Any help would be appreciated.
