I would like to add that this bug also affects 256GB versions of the Samsung
NVMe drives.
The quirk has been added for the 512GB, can we also have one added for the
256GB?
Here is my output of nvme-cli

Title:
APST quirk needed for Samsung 512GB NVMe drive
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Yakkety:
Fix Released
Status in linux source package in Zesty:
Fix Released
Bug description:
APST support just landed in the latest Zesty kernel (4.10.0-14.16) as
part of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664602.
That patch has a quirk for certain 256GB Samsung drives found in Dell
laptops that do not behave well when APST is enabled. I am
experiencing the same symptoms with the same model laptop except with
a 512GB Samsung. Prior to manually disabling APST the drive would die
and system would go down in flames with I/O errors within 20 to 40
minutes of boot.
