href="show_bug.cgi?id=102803">Bug 102803</a> is the same issue.
I'm running 4.14.15 very close to upstream (gentoo-sources). I tested with
your nvme_core option on the kernel command line and reproduced the issue
(verified it was disabled via 'nvme get-feature -f 0x0c -H /dev/nvme0 | grep
APSTE'. So that's not a workaround.
Right now I'm booted with rc6 disabled to verify that 'fixes' it.</pre>
