Public bug reported: Hi,
I have a brandnew HP Microserver Gen10 with a freshly installed and almoste bare Ubuntu 16.04 and its 4.4.0-98-generic kernel, two additional disks, and zfs. Runs stable, but during shutdown it happened many times that the kernel crashed and the machine completely froze (or hung in shutdown). Since the machine was dead then, the only option to get the details was a "screenshot" of the screen (as attached). I've running a similar configuration on other machines, including older Microserver models, but never saw that on any other machine.
