I am sorry about the delay in uploading the logs. Update: * I wanted to experiment on many things before I conclude this as a kernel defect.
* A few firmware updates (including BIOS) were done. * After these fw updates, I am unable to hit the same crash/hang issue. Rather, I only see couple of my stress threads getting killed by oom- killer and other threads exiting gracefully after 20hrs of I/O stress run. This seems ok for me. I've tried 5 full runs now. * # uname -r 4.13.0-32-generic This is the same kernel where the hang was previously seen during the 20hr stress. Give me a couple of days to get back here and update if this looks to be a genuine Xenial defect.
