--- Comment #6 from Theodore Tso (tytso@mit.edu) ---
Note that what you found in your stack exchange search was from five years =
ago,
and described a workaround in a Linux kernel versiojn 4.10.   In addition to
manually disabling APST (a quirk for a very specific Samsung SSD which has
since been added to newer kernels), other suggestions in the stack exchange=
 or
linked web pages included " removing SDD, blowing air into M.2 connector and
reinserting it back" and "switching off the 'UEFI Secure Boot' setting in t=
he
BIOS"

All of which is to say that the symptom is caused by an I/O error, and there
are many potential causes for an I/O error --- everything from missing quir=
ks
(to work around broken firmware / hardware design) to bad connections to
misconfigured BIOS settings to just plain broken hardware.

This is why blindly web searching based on symptoms can often lead to
misleading results; an abdominal pain could mean anything from indigestion,=
 to
a pulled muscle, to an infected appendix, to a heart attack.  It's also why=
 I
am not fond of people finding bug reports on the web and assuming that anyt=
hing
that has the same symptom must have the same root cause.....
