Public bug reported:
Hi,
the system continued just fine after this crash happened on my Yakkety Test
system.
In fact I found that accidentally when running dmesg for something else.
For now I primarily wanted to collect data before loosing it due to a
reboot.
I ran the same workload multiple times before without that anywhere in the log
before.
I checked what else happened at the time and it seems that this was caused by
an DPDK enabled openvswitch that I stopped in the cleanup for the next test.
That process before was interrupted being only half setup due to an issue in my
setup script.
But I had cases like this a lot and never hit the issue.
So for now if nothing obvious to you is found please consider this just
a data store to find it again if more similar cases show up.
Since there was no crash, full stop or anything I couldn't provide any
dump data (at least I know now way that would still help)
