Public bug reported:
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.
