Title:
kexec reboot = NMI: PCI system error (SERR) for reason a1 on CPU 0
Status in linux package in Ubuntu:
Expired
Bug description:
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.
System is Dell XPS M1530, Core 2 Duo T9300, 4GB RAM
