APST quirk needed for PM951 Samsung 1TB NVMe Drive
To manage notifications about this
I have the same problem on Thinkpad X1 Carbon 5th gen with NVMe drive. I
get read-only rootfs every time I suspend my laptop (e.g. by closing the
laptop's lid).
Things were fine under Ubuntu Xenial 16.04. Once I upgraded to the

XPS 9550 is the consumer version of Precision 5510, right?
I did some test on Precision 5510 a while back and the BIOS did fix the issue.

firmware version.

Sorry - I've hit a hiccup. `apport` wants me to file extra information (as
uploaded above, twice) but upon running at the command line it notes:
