Comment 3 for bug 1597908

This system crashes making apport-collect not possible after the fact, though I confirm it is a bug. As the upstream nvme driver maintainer, I can recommend either which driver commits need to be reverted, or which kernel commit needs to be cherry-picked (preferring the latter :)).

Here is a snippet of stack trace:
