apport information ** Tags added: apport-collected xenial
** Description changed: On 16.04 with linux-image-lowlatency-hwe-16.04 amd64 (currently 4.13.0-30-lowlatency) with kexec-tools default-configured to handle reboots with the current kernel version (no GRUB detect) and /proc/cmdline. The system freezes either permanently (requiring a hard power-off) or for tens of seconds, showing (copied from a photograph): kexec_core: Starting new kernel nouveau 0000:01:00.0: DRM: GPU lockup - switching to software fbcon NMI: PCI system error (SERR) for reason a1 on CPU 0. Dazed and confused, but trying to continue Due to the nature of the failure there is no additional logging or clues. I tried "nopti" in case recent 'Meltdown' changes were responsible but it still happens. I've only just enabled kexec on this system so have no historical indications of it having worked.
