Applied the patch from -proposed: root@Ubuntu1804:~# echo "deb http://archive.ubuntu.com/ubuntu/ bionic-proposed restricted main multiverse universe" | tee -a /etc/apt/sources.list root@Ubuntu1804:~# apt-get update root@Ubuntu1804:~# apt-get dist-upgrade root@Ubuntu1804:~# shutdown -r 0
Verified that the -proposed contains fix: root@Ubuntu1804:~# objdump -d /lib/modules/$(uname -r)/kernel/drivers/nvme/host/nvme.ko | grep -A 50 __nvme_submit_cmd\>: | grep fence adf: 0f ae f8 sfence ae6: 0f ae f0 mfence
(second mfence is the one added by patch)
Verified that the patch solves the issue:
./orion -run advanced -num_large 0 -size_small 8 -type rand -simulate concat -write 40 -duration 120 -matrix row -testname gcp_test
(no hang after 36 hours)
I assume that the same patch will be added to Xenial and Cosmic.
