Bill,

Maybe it is not the point..., but have you considered the option of
running 'badblock' (non-destructive/destructive after dd'ing to backup)?
even on swap space? 

As you said, it was after 4.4 update, new space on disk used to store
new updates, maybe... 

Sure im wrong... but btw... sometimes when i have disk issues i also
check temperature for transient failures due mobo/processor...

What im doing (up to anybody tells me other thing) is to post the bug at
Centos Bug Tracker, this is what we are using, this is where i think we
have to toss the bugs, well, my way only of interpreting things...

Have good luck Bill
