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.
