Bug Description

Dear Canonical,

There is a bug on nvme device driver that causes EEH to be broken during an event. This causes an OOPS on the nvme, and make the entire machine unavailable. This is the trace that we see during this problem:

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I used kernel 4.4.0-25-generic from xenial-proposed, and was able to perform 129 iterations of the leaf-eeh tool without crashing. Issue looks fixed with that kernel, thanks!
Moving to verified...
