photo of ht ekernel panic messages/ NMI
With all kernels 4.l5 when I start a shutdown with "shutdown -r now" from the console (ALT-CRL-F1) I receive a kernel panic with a NMI.
System is a HP proliant ML350p with tumbleweed with default kernel.
System updated always with "zypper dup"
No message in logs found
Video is a Nvidia Quadro 4100m running with nouveau driver and two screens
last line on screen is
nouveau:0000:0a:00.0 DRM: GPU Lockup _ switching to software fbcon
After some time (10-15 seconds) the system starts all fans at maximum speed.
I must then do a hard reset.
I attach here a screenshot with the kernel Panic (jpg)
