I built a test kernel with the patch mentioned in the description. The test
kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1753371
Can you test this kernel and see if it resolves this bug?
Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.
Thanks in advance!

hi Naveed,
nvme subsystem-reset calls EEH recovery path. Is EEH recovery working
with Bolt on this machine?
Thanks,
Wendy

The following patch should fix the issue.

nvme/2018-February/015745.html
It should be accepted into community soon. Keith has agreed to queue
up for 4.16.
