--- Comment #119 from Guenter Roeck (linux@...ck-us.net) ---
I think I need some education. It has been suggested suggested several times -
both here and elsewhere on the web - that the problem might possibly be caused
by bad drives. Yet, I don't recall a single instance where a disk error was
reported in conjunction with this problem. I most definitely don't see one on
my systems.

Can hard drives and SSDs nowadays fail silently by reading bad data instead of
reporting read (and/or write) errors ? I would find that thought quite scary.
Can someone point me to related literature ?

In this context, it seems odd that this presumed silent disk error would only
show up with v4.19.x, but not with earlier kernels.
