Public bug reported: Ubuntu freezes after some time because of an error with the PCIe bus (see journalctl.log).
After changing a kernelflag in /etc/default/grub 'GRUB_CMDLINE_LINUX_DEFAULT="quiet pcie_aspm=off"' the problem is solved. Desired outcome: implement this fix (automatically). I hope apport added everything important. If you have any further questions, feel free to contact me.
