@Kai-Heng Feng: I will test now with 6000, so far it looks good, but
hadn't much time to test during the holidays. I report back later this
day.

Title:
APST quirk needed for Samsung 512GB NVMe drive
Status in linux package in Ubuntu:
Incomplete
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.
